Lap Former Machine
Lap Former Machine of spinning mill is used for lapping cotton and forming compact lap from drawn sliver by drawing & drafting to feed the combing machine. The lap of 30 inch wide is wound on to bobbin and cotton wool. The lap former machine is not use in the carded yarn process because it is used for lapping yarn by lapping process. Former meaning make laps of various counts for Carding Machine of textile industry.
Application of Lap Former Machine for Lapping Process:
This machine is used for lapping process wool and further opening and impurity separating cotton human made fibre blend and midlength chemical fibre balow 77mm and making the lap and lap joint of various counts for carding machine.
