ABSTRACT:
Apparatus for treating lengthwise traveling material has a material driving member provided with alternating grooves and lands extending parallel to the direction of drive of the material, presser means to press the material against the lands, and a retarder member downstream of the presser member for deflecting the material away from the driving member, the retarder member having an edge portion extending across the path of travel of the material provided with teeth extending into the driving member grooves with clearance from the groove walls, and intervening slots receiving therethrough the lands of the driving member with clearance from the slot walls. The construction avoids snagging of the material by, or diving of the material under, the retarding member, and wear of the retarder member.
