Abstract
The lap winder has two rotatable lap rollers which support a lap during winding. A drive motor drives the lap rollers through the intermediary of a transmission or gearing. A brake mechanism acts on at least one of the lap rollers or on an element co-rotating or fixedly connected for rotation with one of the lap rollers. When the lap winder stops then the brake mechanism is actuated and takes-up the kinetic energy of the lap rollers and that of the lap supported on the lap rollers. The braking forces for the lap rollers and for the lap therefore do not have to be transmitted through the transmission or gearing. There are thus avoided heavy loading and wear of the transmission or gearing.
Claims11
A lap winder for producing laps from slivers, comprising:
- two rotatable lap rollers for supporting a lap during lap winding;
- a transmission cooperating with the two rotatable lap rollers;
- fiber material supply means for infeeding fiber material to the two rotatable lap rollers for forming the lap;
- means for branching-off power from the transmission for driving the fiber material supply means in dependence upon operation of the two rotatable lap rollers;
- a drive motor for driving the two rotatable lap rollers by means of said transmission;
- and
- at least one brake mechanism cooperating with at least one of the two rotatable lap rollers for stopping rotation of the two rotatable lap rollers, whereby, when the drive to said transmission from said drive motor is disengaged, said at least one brake mechanism is applied for preventing transmission or kinetic energy of the lap rollers and the lap supported thereupon to the drive motor upon braking of the lap rollers and the lap supported thereupon to a standstill, and thus minimizing loading of the transmission.
