Sheet Product Wrapping Apparatus

Abstract

The apparatus includes a clamp lever 3 by which sheet products 1 are clamped near one edges thereof after being stacked. The clamp lever 3 is rotated at an angle of 180° so that the sheet products 1 are swung and turned over by the clamp lever 3 . The apparatus further includes a horizontal member 13 by which the sheet products 1 are received and supported, a press bar 14 being pressed against the sheet products 1 and then moved along the sheet products 1 . The sheet products 1 are therefore pushed and smoothed out by the press bar 14 . The sheet products 1 are wrapped with a wrapper 17 after being smoothed out.

What is claimed is: 
     
         1 . A sheet product wrapping apparatus comprising:
 a clamp lever by which sheet products are clamped near one edges thereof after being stacked:   a lever drive by which the clamp lever is rotated at an angle of 180° about a horizontal shaft extending parallel to the one edges so that the sheet products are swung and turned over by the clamp lever above the horizontal shaft:   a horizontal member by which the sheet products are received and supported after being swung and turned over;   a press bar extending parallel to the horizontal shaft; and   a bar drive by which the press bar is pressed against the sheet products and then moved along the sheet products away from the clamp lever on the horizontal member, the sheet products being pushed and smoothed out by the press bar,   the sheet products being wrapped with a wrapper after being smoothed out.   
     
     
         2 . The apparatus as set forth in  claim 1  further comprising:
 a vertical member disposed above the horizontal member, the sheet products being engaged with the vertical member at the other edges thereof after being swung and turned over, 
 the press bar being moved along the sheet products to pass between the vertical member and the horizontal member so that the sheet products are guided by the vertical member to be folded by the press bar, the sheet products being wrapped with the wrapper after being folded. 
 
     
     
         3 . The apparatus as set forth in  claim 1  wherein the sheet products have a length, the press bar being moved to the other edges of the sheet products so that the sheet products are smoothed out throughout the length, the sheet products being then wrapped with the wrapper. 
     
     
         4 . The apparatus as set forth in  claim 1  wherein the clamp lever is spaced from a discharge position from which the sheet products are discharged, a stopper and a receiver being interposed between the clamp lever and the discharge position, the sheet products being discharged successively and engaged with the stopper at one edges thereof to be stuck on the receiver, the sheet products being then clamped by the clamp lever, the clamp lever being rotated to opposite side of the discharge position, the sheet products being swung to and turned over on the opposite side of the discharge position.
