Abstract
Small tear-open strips 10 are fed to a sheet 11 of packaging material in a timed sequence and applied to the sheet by reciprocating conveying members 22, 23 which only grip in one direction, so that the strip is pulled along in steps. As a result, a high performance and especially the transition from intermittent conveyance of the strip to continuous transport of the sheet of packaging material are possible.
