Wrap Foil Dispenser

Abstract

A wrap foil dispenser, comprising a base plate, provided with a channel, through which a blade glides. As part of a cutter assembly which glides along a guide, the blade slides and cuts the foil without touching the plate. The cutter assembly includes an arm which ensures that the blade engages the foil. In case the plate is laterally tilted or the cutter is slid by hand, the cutter assembly moves along a channel to which cutting edges of the blade are placed inside. When the blade is moved, the foil, placed on the upper side of the channel, is cut. The blade's vertical position is uniform as a result of the cutting assembly pressing through the arm's own weight which is limited by a buffer element. The dispenser may include a rotating support, provided with two conical elements that ensure mounting of foil rolls having various dimensions.

1 . Wrap foil dispenser for foil rolls preferably wounded on a cylindrical core, comprising:
 a base plate  2  having two lateral walls  17  and  18 , wherein, on the lateral walls  17  and  18  there are supporting elements  21  and  22 , for supporting a rotating support  12 , and also supporting elements  19  and  20  to fix a sliding guide  4 , on which is glided a cutter assembly  5 , provided with a blade  6  in the inferior side, the base plate  2  being provided with a channel  3 , parallel with the guide  4 , upon which the cutter assembly  5  is gliding, the peak point “c” of the blade  6  is positioned inside the channel  3 , with the cutting edges “a” and “b” at a level established at the level of the plan of the plate, the foil roll being positioned upon the base plate  2 , the level of the cutting edges of the blade being determined by a buffer element  10 .   
     
     
         2 . Dispenser according to  claim 1  wherein the buffer element  10  has a shape of a disk that it is turning up upon a shaft  9  of the cutter assembly  5 , the disk's radius defines the distance between the cutter assembly  5  to the plate  2  and the depth the blade  6  gets into the channel  3  of the plate  2 . 
     
     
         3 . Dispenser according to  claim 1  wherein the cutter assembly  5  is a heavy element and it is pressed by its own weight, ensuring the pressing and the position of the blade  6  on the plate, respectively, the position of the cutting point “c” inside the channel  3 , the result being the foil cutting, the weight of the cutter assembly  5  ensuring also the force, necessary for the lateral sliding on the guide  4 , when the plate is tilted to one or the other end of the guide  4 . 
     
     
         4 . Dispenser according to  claim 1  wherein the rotating support  12  comprises a support pipe  13  and two conical elements  24  having the peaks positioned face to face, each of them provided inside with a cylindrical hole “g”, allowing their mounting on the pipe  13 , the distance between the two conical elements  14  mounted on the pipe  13  being adjustable. 
     
     
         5 . Dispenser according to  claim 1  wherein, it comprises a rotating pipe  25  placed between the rotating support pipe  13  and the sliding guide  4 , in order to guide the foil  16  at the level of cutting edges of the blade  6 .
