The reversing gear can essentially consist of a drive shaft With gears attached to it «of an output shaft also with two gears, which are however freely rotatable, as two electromagnetic clutches, which are firmly connected to the output shaft and interact with its gears, as well as another gear on a separate shaft, which is between two associated gear wheels of the input and output shafts Intermediate business et is, consist · A gear pair stands with its teeth directly meshing · This pair preferably consists of a large diameter gear that sits on the drive shaft seated and a gear wheel of small diameter · the output shaft. This achieves a large translation, which results in a high speed of the slide and is used for the return of the slide especially simple reversing gear can be formed by omitting the separate shaft with the further gear is and the two remaining, mutually assigned gears of the input and output shaft by a drive chain get connected. The gears can then of course consist of simple chain wheels.

A magnetic brake, which is connected to the clutches, is expediently arranged on the output shaft and an immediate standstill or release of the output shaft causes. The slide itself is driven by the output shaft via a pinion and a rack. In order to be able to make good use of the spatial conditions when accommodating the reversing gear, between slide and reversing gear a chain gear is used »
