Lap Former Machine | Features of Lap Former Machine

Lap Former Machine:
The lap former has, furthermore, the task of forming the interfacing or lap , which is employed to feed the combing machine. The lap is obtained by doubling a certain number of slivers (from16 to 32)previously subject to a drawing passage. The slivers are fed side by side, passing , through rollers and stop motion. The slivers enter the drafting section and then calendar ' section to produce a compact lap. Finally the lap is wound on to bobbin. In the lap former, the material under goes a light draft of around 1.5 to 2 times one a drawing aggregate of the type 2 on top of 3 cylinders.
