THE LONGEST ROVING FRAME FOR MAXIMUM PRODUCTIVITY

The productivity of the machine increases with the number ofspindles The F and F roving frames are designed for upto spinning positions at a spindle gauge of mm

DRIVE SYSTEM FOR HIGH OUTPUT AND REDUCED MAINTENANCE

The proven multi-motor drive system has been optimizedfurther The differential gear has been eliminated Spindlesand flyers are driven directly by individual servomotors Thecontrol system ensures synchronized running throughoutpackage buildup The main features are reduced maintenancelower energy consumption and speeds of up to rpmmechanical The drives are controlled by frequency convertersand thus especially gentle in their treatment of the materialControlled machine stop is assured in the event of power failure

IMPROVED RUNNING BEHAVIOR WITH INDIVIDUAL ROVINGMONITOR

It is advisable to equip the roving frame with the ROJindividual roving monitor optional especially in the case ofmanmade fibers blends dark-colored raw material and longmachinesIts main features are

no incorrect stoppages due to fiber flyindividual automatic control and logging of roving ends downprevention of lap formationstatistical analysis for systematic improvement of runningbehavior

This results in a considerable increase in roving frameeffi ciency

SIGNIFICANT ENERGY SAVINGS

The energy saving package reduces energy consumption on theroving frame by at least kWh thus reducing manufacturingcosts per kg of yarn produced

FURTHER ADVANTAGES

The energy saving package offers further advantages Theinstallation of the roving frame itself is simplified Installationcosts are lower since no holes have to be made in the floorand the number of parts to be installed is reduced Operationof the roving frame during production is also simplified Filtercleaning is eliminated and accessibility of the drafting systemis visibly improved

Energy saving package

ECONOMY

TECHNICAL APPROACH

The technical approach of the energy saving package is basedon a basic machine without an extraction system The travelingcleaner and the ROJ individual roving monitor in combination

with the cleaning device and the fixed strippers for the bottomrollers ensure trouble-free running and adequate cleanlinessin the drafting zone The smooth surface under the draftingsystem helps to maintain cleanliness

Installed power is reduced by kWh since the extractionmotor is dispensed with

F MANUAL DOFFING WITH DOFFING AID

Manual doffi ng is facilitated by a doffi ng aid For this purposethe bobbin rail with the full roving bobbins is lowered and tilt-ed This enables the bobbins be removed easily

Specifying the roving end

SPECIFYING THE ROVING END

The F roving frame is supplied with the roving end in themiddle of the roving bobbin function as standard equipmentOn request the roving end can also be specified as top bunch

Top bunch is ideal for combining the manual roving frame withautomated roving bobbin transport systems In this case theroving bobbins are transferred manually to the transport sys-tem thus handling the material especially gently The end ofthe roving is fixed in position by the top bunch and cannot de-tach itself spontaneously

DOFFING TIME OF LESS THAN MINUTES WITH THE FULLY

AUTOMATED F ROVING FRAME

Development of the fully automated F roving frame hasresulted in a significant reduction in doffi ng time Separate

actuation of bobbin rail and doffer rail is the basis for theshortest doffi ng time compared with other products Bothprocesses are controlled by frequency converters and cantherefore be performed synchronously and independently ofeach other While the bobbin rail with the full bobbins is low-ered and placed on the slide the doffer rail leaves its idle po-sition and is lowered slowly The slide with the bobbin railmoves forward out of the machine

F Shortest doffi ng time


Fig Bobbin rail moves out doffer rail with emptytubes is lowered

Fig Removal of full bobbins Doffer rail with bob-bins and tubes is raised shifting lowering andcreeling of the empty tubes

The ability to control the sequences of motion separately en-ables the doffi ng process to be shortened considerably anddoffi ng times of less than minutes are realistic Doffi ng timeis independent of machine length ie minimum doffi ng times

are also applicable to long machines

The operation of the doffer is also assured during mainte-nance and other transport system downtimes The doffer railwith the full bobbins can be lowered to a convenient workingheight so that the bobbins can be removed manually

GENTLE INFEED SLIVER GUIDANCE

The slivers are drawn out of the cans by hexagonal rollers withgeared drives and fed to the drafting systems This preventsdrafting errors splitting or damage and increased hairiness of

the sliver

HIGH QUALITY STANDARDS

The pneumatically loaded drafting system is an important tech-nological component Constant pressure monitored by a sensorensures maximum roving uniformity along the entire length ofthe machine Pressure is centrally adjustable and infinitely varia-ble Automatic relief of loading on the guide arms is also central-ized This prevents permanent deformation of the top rollers

UNIFORMITY THROUGH ROVING TENSION CONTROL

Roving tension is monitored and controlled without contact

The proven ROJ system is used for this purpose Roving tensionis controlled and kept constant throughout bobbin buildup bymeans of two sensors and a microprocessor This ensures highyarn uniformity and prevents prevents false drafting

With the launch of the new generation of roving frames therange has been expanded to models the F model withmanual doffer and the F with fully automated doffer Both

models are available with gauges of mm and mmWith a gauge of mm the maximum number of spindles is With a gauge of mm the maximum number of spin-ning positions is A machine with spindles at mmgauge is shorter than a machine with spindles and mm gauge This opens up interesting possibilities with regardto layout and flexibility

HIGHER QUALITY AND LOWER COSTS

Roving bobbins are a delicate intermediate product The outer-most layer of roving is completely unprotected and is thus ex-posed to considerable risk of damage Furthermore all defects

in the roving are transferred to the yarn and are often also vis-ible in the end product Ensuring roving quality as such as wellas the calculable labor cost savings are good reasons for in-vesting in automated transport systems
