Incoherent product volumetric batching device for high speed packaging machines

Claim 1

Device for dispensing volumetric batches of incoherent material comprising a horizontally arranged material dispensing cylinder which is rotatable about its horizontal axis and is provided with a plurality of radially outwardly open pockets, a hopper for the material positioned at the top of the dispensing cylinder and adapted to feed by gravity incoherent material into the pockets as the cylinder rotates, a roller idly supported adjacent and downstream of said hopper and adapted to deviate a strip of packaging material around the dispensing cylinder in the direction of rotation of the latter so as to partially wrap said cylinder, and means for driving the strip of packaging material including a pair of counterrotating entraining rollers through which the strip passes and provided with complementary recesses, wherein according to the improvement said entraining rollers have their rotation axes lying in a vertical plane and their contact line lying in a horizontal plane tangential to the lower point of the dispensing cylinder so that the strip defines a horizontal run extending from the dispensing cylinder to said entraining rollers for receiving the volumetric batches of incoherent material deposited thereon from said pockets as the dispensing cylinder rotates, said volumetric batches during passing said entraining rollers being accomodated in said complementary recesses.
