摘要： An apparatus (10) for performing a work operation on sheet material (12) includes a plurality of drive wheels (42) for driving the sheet material (12) in cooperation with a plurality of pinch rollers (36) along a feed path (30). Each of the drive wheels (42) includes a drive surface (54) having a plurality of primary teeth (60) and a plurality of secondary teeth (62). Each primary tooth (60) includes a top surface (76) and a plurality of primary contact points (78) to engage the sheet material (12). Each secondary tooth (62) includes either a secondary contact line (92) or a secondary contact point (90) that come into contact with the sheet material (12) to provide additional driving force and to prevent the sheet material from being perforated by the primary teeth (60). The primary teeth (60) and the secondary teeth (62) of the drive wheels (42) engage the sheet material (12) to advance the sheet material along the feed path (30). The drive surface (54) of the drive wheels (42) of the present invention minimizes slippage of the sheet material (12) in the drive apparatus (10) without damaging the sheet material (12).

摘要翻译：一种用于对片材（12）进行加工操作的装置（10）包括多个驱动轮（42），用于沿着进给路径（30）与多个夹送辊（36）配合驱动片材（12））。每个驱动轮（42）包括具有多个主齿（60）和多个副齿（62）的驱动表面（54）。每个主齿（60）包括顶表面（76）和多个主接触点（78）以接合片材（12）。每个辅助齿（62）包括与片材（12）接触以提供额外的驱动力的二次接触线（92）或次级接触点（90），并且防止片材被初级牙齿（60）。驱动轮（42）的主齿（60）和副齿（62）与片材（12）接合，以使片材沿着进给路径（30）前进。本发明的驱动轮（42）的驱动表面（54）最大限度地减少了驱动装置（10）中的片材（12）的滑动，而不会损坏片材（12）。
