DEVICE FOR CHANGING SLIVER CANS IN PRESPINNING MACHINES, IN PARTICULAR FOR A DRAWING FRAME

摘要

The can changing apparatus operates so that the full can and empty can are arranged to move in guide paths which are at a right angle to each other. A simultaneous exchange of the cans takes place with one can being shifted at a constant speed while the other can moves with a speed characteristic which corresponds to a tangent function. The support members on which the arms for pushing the cans are mounted are connected, for example by a rigid curve rod, a resiliently bendable rod, or a linked arm such that one support member moves the other.
