Jigger with large area loader - has stepless gearing between input elements of two winding roller gear trains

摘要

The two gear trains of the winding rollers are synchronised in such a way that the output speed of the first one is matched to a single output speed of the other one. Pref. the gearing between the two input elements consists of a conventional V-belt assembly, with a control sheave on the input shaft of one of the other gear trains and a spring sheave on the input shaft of the other one, the V-belt itself running between these two members. The design avoids limiting the size of the workpiece matl. rollers.
