Abstract: An in-line machine for attaching elongated, flexible closure tie elements to the individual bag portions of a laterally folded plastic film web being continuously discharged from a bag forming station, and being forcibly captured by a winder mechanism, engages and drives the moving web toward the winder mechanism by means of mutually spaced inlet, central and outlet drive rollers. During operation of the machine, first and second slack portions of the film web are respectively positioned between the inlet and central rollers, and between the central and outlet rollers. These slack portions are held in vertically looped configurations by a downwardly directed, yielding vacuum force applied thereto. The inlet and outlet rollers are driven at identical speeds corresponding to the constant linear film web output speed from the bag forming station.

Abstract: A separator for segregating alternate sheets of paper traveling in a sequential stream and directing them into different exit passages comprising a housing, a guide and a bi-stable apparatus. The housing defines an entry passage and a pair of exit passages. The guide is constructed for alternately deflecting the sheets in said stream into different exit passages. The bi-stable apparatus mounts the guide between the entry and exit passages of the housing so that the guide has two stable positions and the guide shifts between these positions in response to a sheet of paper passing by it into one of the exit passages. Sheets of paper enter the separator through the entry passage in the housing and are deflected by the guide into one of the two exit passages depending on the position of the guide at the time the sheet enters the separator. As individual sheets of paper travel past the guide and engage it, they cause it to shift to its other stable position.
