ABSTRACT:
In the course of the installation or removal of an opening roller, the opening fittings, which for example consist of many pointed needles or a sawblade-shaped metal strip, represent a considerable risk of injury. So far no devices are known in connection with opening rollers driven by individual motors which, make unintended starting of the rollers impossible while being replaced and serviced. In accordance with the invention, an opening device has a locking and unlocking device which assures an orderly operation of the opening roller driven by an individual motor and also assures that while servicing or installing the opening roller no danger of injuries can occur, for example because of an unintended starting of the opening roller.
