Title: ELLIPTICAL SYNCHRONOUS BELT DRIVE
Abstract:
The invention relates to a device for closing a tubular or pouch-type packing wrapper filled with stuffing, especially sausage meat. Said device comprises means for tightening the packing wrapper and forming a top section free of stuffing, closing means for placing and closing at least one closing clip around the top section, and a drive for the tightening means and the closing means. Said drive comprises a gearbox (200, 300) that has a variable transmission ratio and transforms a uniform driving motion into a periodical, variable output motion, the transmission ratio of said gearbox being such that the output speed is slower during the positioning of the closing means than during the tightening and displacing processes.
