摘要

NO.730/MAS/2001 ABSTRACT An apparatus for forming lap in a lap package production machine is provided. It comprises a guide head assembly with plurality of guide heads (1), a top traverse (2) and bottom traverse (3) rigidly fastened to the said guide head (1). Lap discs (5) are provided on the ends of lap disc shafts (4) located in the guide heads (1). The guide head assembly is guided on guide shafts (8) supported by supports (7) rigidly fixed to frame of the lap package production machine. Electro pneumatic loading cylinders (10) with cylinder holders (11) are rigidly connected to the guide heads (1) and piston (12) of the loading cylinder (10) is hinged to supports (9) rigidly fixed to frame of the lap package machine. A sensor (S) is provided for providing a signal proportional to the length of the lap wound and connected to an electronic controller (C) to provide a signal corresponding to the diameter of the lap package from time to time to a microprocessor (P) which regulate the load applied by the said loading cylinders (10) and control the lap winding speed through variable speed drives (DRI and DR2}.
