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.
