FOI@WORD
This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the FootwearSectional Committee had been approved by the Chemical Division Council.
A series of Indian Standard on lasts have been compiled for manufacturers of lasts and footwear. This standard,which is fifth in the series of standards on last, covers the requirements and methods of sampling and test forplastic lasts for use in the footwear industry. Other standards formulated on lasts are:
IS No. Title
5520:1969 Lasts, wooden, for heavy duty boots
4512:1978 Footwear lasts, wooden (first revision)
7329:1974 Metal last for safety rubber canvas ankle boots
10089:1981 Metal lasts for knee boots
It is mainly the forepart of the last that alters with fashion. The rear portion which is concerned with the leastmobile part of the foot does not change with fashion. The modern factory practice is to standardize the backportion for a particular heel height. The lasts are generally grouped according to their principal characteristicsand according to the unit operations to which they are put.
For plastic lasts, generally a blend of high density polyethylene (HDPE) and low density polyethylene (LDPE)is used but many use only HDPE for this purpose. The objective is to make the lasts able to withstand the effectsof temperature, pressure and chemicals used in making shoes on machine.
In this standard, rationalized values of English sizes which is in vogue in this country has been prescribed. It ishoped that the shoe industry which is presently following English sizes or Paris point (exclusively used at themoment for export trade) will progressively switch over to an internationally acknowledged rational metric sizesystem.
There is no 1S0 Standard on the subject.
The composition of the Committee responsible for formulation of this standard is given at Annex C.
For the purpose of deciding whether a particular requirement of this standard is complied with, the final value,observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance withIS 2:1960 ‘Rules for rounding off numerical values (revised)’. The number of significant places retained inthe rounded off value should be the same as that of the specified value in this standard.

After the reproductionby the copying lathe, the rivets forma slight bump on the lastwhere marking can be done with the help of the jig easily andaccurately.
6.2 Articulated or Detachable or Hinged Last
6.2.1 The last after rough turning shall be cut intotwo sections, the back and the forepart. Both thesepieces shall be joined together again with the help ofelliptical shaped gap-spring hinges.
NOTE — There are many type of hinges used by differentmanufacturers, other than elliptical type. Hinge should fultil tberequirement of shoe manufacturing (that is unlasting of shoe bymachine).
6.2.2 To enable the last to bend at this hinge plate orspring and to make the operation of last slipping easy,the portion having the hinge plate or the spring shallbe cut into a V-shaped, making enough room for theback part of the bend, thus shortening the overalllength of the last and take space at the back for easyremoval of the last from the shoe (see Fig. 8).
NOTE — The manufacture of infant lasts (sizes 1to 8Yz)withouthinges shall be permitted.
6.2.3 The diameter of the pin hole shall be 5 mm forchildren sizes 4 to 11!4 and 6 mm for all other sizes.The distance between the two holes (measuring fromthe centre of the hole) shall be 39 mm for childrensizes 4 to 11% and 50 mm for all other sizes.
6.2.4 The focal or centre point of joining “onwhichthese sectional cuts are performed shall be located20 mm above the feather edge of the shank portion ofthe last. The distance shall be maintained for all sizesof lasts. The line of centre of joint or the distancebetween this focal point and seal edge shall be 79 mmfor junior size 4 last with variation of this length forconsecutive sizes by 2 mm.
6.2.5 Both the holes shall be 3 mm below the focal orcentre point of joining (counting from the centre ofthe hole along the shortest distance).
6.2.6 The length of the lower cut at the bottom of thelasts shall be 74 mm for junior size 4 last with 2 mmdistance difference for each consecutive sizes.
6.2.7 The total length of the V-cut or angle cut shallbe 40 mm for junior size 4 last with variation of thislength for consecutive sizes by 2 mm. The length of
the top shall be 60 mm for junior size 4 with 1 mmdifference for contiguous sizes or the angle of V-cutwill be 43° base will be EF and from point E, H willbe 43° from EF line that is DEF will be 43° (Fig. 8).
6.2.8 The diameter of round cutting shall be 18 mm forchildren size 9 to 11% and 20 mm for all other sizes.
6.2.9 Thickness for mortizer chain for slot cutting forfixing hinges shall be 0.2 mm bigger than the thicknessof gap spring hinges.
NOTE — For eff]cient and correct location for the centre ofjointangle cut, round cut and cut at the seat, round headed rivets ornails are inserted on specified position on the body of the turningmodel. Atter reproduction by the copying lathe the rivets formaslight bump on lasts, where marking can be done easily andaccurately.
6.3 Galvanized Bottom Plates
In the metallic plates, holes shall be pierced with acountersunk for passage of nails and screws fasteningthe plates.Any of the following methods may be followedfor attachment of the plates to the bottom of the last asagreed to between the purchaser and the supplier.

11.1.3 On the superimposition, the profile pattern of thelongitudinal bottom section (generally called ‘bottomprofile’) shall coincide with the axis of the bottom of thelast along with the contour of the heel back curve.
11.1.4 Measurement of the last shall be done by astandard last measuring tape (a tape of non-variabledimensions with fine metallic wire inside); the widthof the tape shall not be more than 10 mm.
11.1.5 During measurement of the joint and instep girth,the measuring tape shall be placed on the last in such away that the measuring edge of the tape fits closely andlies flat on the last along the line of measurement.
11.1.6 During measurement of instep girth of the lasts,the measuring edge of the tape on the comb shall comein contact with the marked point. Near the bottom,the tape shall settle in the most concave part of thelast in such a manner as to give during thismeasurement of the last the smallest size.
11.2 The location of the joint shall be measured asdesmibed in Annex B.
11.2.1 An approximate position for location of the balland instep girth measurement in insole pattern isshown in Fig. 13. This system requires little skill andcan be performed without the help of any apparatusand as such may be adopted as a standard practice.
NOTE — Although the joint girth measurement is takendiagonally in a traverse direction, makers of lasts take thismeasurement at arbitrary points to enable them to place themeasuring tape flat to the last. Generally this is taken in either theinside or outside point but never both.
11.3 Following the system described above, forchecking the correctness of position of pin-points, the
bottom of the last and the insole, checked by markedlines is superimposed so that starting from the toe partit coincides all over with the bottom of the last.
11.3.1 Pin-points at the joints (inside and outside) shallbe exactly located on the last at the ends of lines abovethe contour (feather edge) of the lasts at a distance of10 mm.
11.3.2 Correctness of the position of the pin-pointslocated on the body of the last at the base of the instep(along the centre line of the last) is checked either bythe measuring tape with the help of two pin-points ofthe joints for measurement of the ball girth; or by thelongitudinal front profile, which with the work pointas put on the last and the coincidence of the pin-pointon the last with the point of the profile is observed.
11.4 For the determination of the correctness of theposition of the pin-point for measurement of instepgirth on the cone of the last, the following method isrecommended.
11.4.1 The position is represented on the last, alongthe middle of the cone, at a distance of 60 mm abovethe ball joint pin-point, located at the base of the instep.This is the standard practice for men’s lasts, practicefollowed for other categories is given in Fig. 14.
11.4.2 To ascertain the girth of the instep, the tapeshould lie flat and close to the last on the selected points.
NOTE—Like the joint meaauremen~ the instep measurementmay not also be located exactly by rule. Half standard strength ofthe last (excluding the difference between tbe length of the insoleand foot), on an imaginary line through the length maybe givenas the approximateposition.The largestgirth at that point probablyanswers the purpose best.

11.5 Checking of the Insole Pattern of Medium Size
In order to check the basic dimensions of the insole, itis necessary to determine the position of points ofmeasurement.
11.5.1 Position of points shall be measured by a specialpattern or template, the construction of which is givenin Annex B.
11.5.2 Test carefully graded patterns of insole beforehand and profile templates of longitudinal andtransverse sections used for checking of the lasts.
NOTE—The actual stick-lengthof last may vary fiequemtlyfromthe standard length of insole pattern. The insole length shall bealways 2 to 3 mm shorter than the stick-length by virtue of theback curve protruding beyond it. The occupied stick length of alast is the distance from the centre of the curve at the back to theextreme tip of the toe. The actual size-stick length is not to beused to denote the foot fitting length of last. For a given shoe orlast size, the foot shall be shortertban the insole by at least 10mmwhen measurement is taken in a sitting position.
11.6 The height of the last and the dimensions of thetube shall be measured by calipers.
IS 15196:2002
11.7 The height of quarter pin mark or vamp workshall be measured by tape or gauge.
11.8 Measurement of Heel Height
Place the last on a level surface, Raise the seat of thelast until the tread line touches the level surface. Thenmeasure the heel height (from the seat position to thelevel surface) (see Fig. 11), Take care that the seat ofthe last rests almost parallel to the ground.
11.9 Mechanical and Other Requirements
Following items shall be tested for mechanical andother requirements by cutting or opening up thelasts:
a)
b)
c)
d)
Dimensions of the tube,
Proper fitting of the tube,
Measuring the position of the tube verticalto the surface of the heel, and
