Abstract

A feeding device is provided for feeding a material to be processed to a working unit present in a sheet processing line. The feeding device includes a frame element which is provided with a gripping device configured to grip the material to be processed for setting off a feeding motion. The gripping device include a transfer element, which is provided with a press member engageable with one surface of the material to be processed, with the press member being located substantially in coincidence with the center line of the material to be processed. The press member is configured to move in lateral direction along with the material to be processed.

1 . A feeding device for feeding a material to be processed to a working unit present in a sheet processing line, said feeding device comprising a frame element having a gripping device configured to grip the material to be processed and imparting a feeding motion thereto, the gripping device including a transfer element having a press member engageable with one surface of the material to be processed, said press member being located substantially in coincidence with a center line of the material to be processed, and said press member being configured to move in a lateral direction along with the material to be processed.  
     
     
         2 . A feeding device as set forth in  claim 1 , wherein the transfer element, together with the press member, is configured to shift in a vertical motion to an engagement with the one surface of the material to be processed.  
     
     
         3 . A feeding device as set forth in  claim 1 , wherein the press member is configured to shift in a vertical motion relative to the transfer element for bringing the press member to an engagement with the one surface of the material to be processed.  
     
     
         4 . A feeding device as set forth in  claim 1 , wherein the transfer element is configured to shift together with the press shoe in a lateral direction to a feeding direction.
