Device for Winding Hollow Plastic Articles,
Abstract
We know of a device for winding hollow plastic articles which contains a mechanism for continuously feeding the plastic blank, e.g., a bar or strip; a rotating mandrel which has the same configuration as the finished article; a mobile carriage driven by a lead screw to impart translational movement to the mandrel relative to the blank feed mechanism; and a common synchronous electric drive for turning mandrel ans the lead screw. The proposed device is different from the known one because the lead screw is linked with a rotating worm wheel which has a drive that is programmed according to the required variation in the winding pitch through time. The difference makes it possible to smoothly vary the winding step while winding the article; this is necessary in order to obtain intricately-shaped articles.
