Material feed and/or compacting device uses globoid pump with helical feed channel and sealing elements fed along helical guide channel

摘要

The device (10) uses a globoid pump (12) with a housing (18) cooperating with a feed screw (20) for providing a helical feed channel (28), into which sealing elements (30) of corresponding cross-section can be inserted via openings in the housing. The sealing elements are fed along at least one helical guide channel (34) at an angle to the feed axis (32).
