BIG FILTER MESH CUTTING FABRIC CUTTING PROCES
take out the mesh roll keep it on a Table with a claen surface
cu the fabric using a separate scissor .for fabric cutting only
cycle time to study approx 3 to 4 min
DECIDE THE MAXIMUM LENGTH WE CAN CUT USING THE SOLDERING ROD PRESENTLY WE USE THE LENGTH OF 450 MM ( MAKE It Round such that maximum 20 mm get wasted )
mark the required lengt of 450 mm with a std scale marking to be done with a thin 1 mm thick marker
hold the fabric end same time keep the roller in position with an holder and an guide to hold the fabric (make a setup for cutting ) without even marking to be done .
free from dust
to weld and cut the tube from fabric
keep the solderinfg rod ready for the welding process
take out the fabirc fold the fabric and align the fabric and
remove the tubes from the fabric one by one then keepthe tubes inone rubber band for each fabric
cycle time to cut the tube from the fabic
UPHefficiency
start sealing and cutitng fabric with the std width aluminium scale 32 mm repeat the process till you complete all the fabric area
then hold the fabric in 3 rows to separate the tubes from the fabric 3 tubes / one time

machin es hould be onbefore the process time required to heat
fabrc should be stored properly to remove easily ( proper storage
1)keeping the scale and aligning the edges are difficult 2) soldering edge profile is like screw driver it should be flat type 1)Table arae Is not sufficient table shred at pesent 2) glass area length & width is not sufficient 3) length of sealing scale should be more then the fabric length.
solution,s
easily retrivable
1)keep a separate table 2)glass area must be suitable3)scale length should be calc and made
take 3 tube from the bunch hold and align the 3 tubes take out the ok sample for the length
start cutting as per the sample length . Alllow the mesh to fall in to a binsee that the side waste gets in to a waste bin every one hour calculate the quantity for prdn monitoring purpose .

solution,s use clips /plastic shcobers of width 50 mm by 500 mm length .can Have a guide TO algn tubes ned to have a go no go type checker
