Apparatus for a intermittent feeding of a strip shaped blank

摘要

The feeding apparatus is driven intermittently by a electric servomotor with a drive shaft. The upper feeding roller is held clamped in a bipartite upper shaft assembly between a shaft portion located adjacent the electric servomotor and a shaft portion located remote from the electric servomotor. The lower feeding roller is held clamped in a bipartite lower shaft assembly between a shaft portion located adjacent the electric servomotor and a shaft portion remote from the electric servomotor. The upper shaft assembly is supported in a rocker. The transmission of the driving force from the electric servomotor to the upper shaft assembly proceeds via a Oldham-type coupling. The transmission of the driving force from the upper shaft assembly to the lower shaft assembly proceeds via spur gear wheels. The connection between the drive shaft of the electric servomotor and the upper shaft assembly is accomplished by a multi-part clamping sleeve device. The one spur gear wheel and a part of the Oldham-type coupling are made integral with a part of the multi-part clamping sleeve device.
