Abstract

Pieces are cut off the end of a long web by first impaling the leading end of the web on a crosswise circulating needle bar that is then moved downstream from a cutting to a holding section. Then at the cutting station another such circulating needle bar and a noncirculating needle bar are poked through the web, with the noncirculating bar being downstream (relative to the displacement direction of the web) of the circulating bar. Then the web is cut across between the two upstream bars and the noncirculating bar and the downstream circulating bar are dropped down to transfer the piece thus cut from themselves to a transverse needle-chain conveyor. Then the circulating bar is moved back from the downstream holding station to the upstream cutting station while the second circulating bar pulls another piece of the web downstream across above the transverse conveyor.
