摘要

The protective cover is provided with at least one drum (1) mounted on a shaft (40). The shaft (40) is connected to a reciprocating slide via drive elements and to a drive gear (2). Furthermore, it has a cover band which can be wound up on the drum (1) and is arranged at the other end of the slide. In order to obtain satisfactory functioning in the event of excessive changes in the slide speed, provision is made for a torsion spring (34) to be arranged between the shaft (40) and the drum (1) and for the shaft (40) to be mounted directly on the machine bed (43). The slide is in constant drive connection with the shaft (40), and the diameter of the drive gear (2) is greater than the drum diameter for the cover band (41). <IMAGE>
