Apparatus for the supply of blanks of packaging material and in particular for the supply and erection of flat folded tubular blanks as packaging cases in 'blister' packaging machines

摘要

An apparatus for the supply from a fixed store of blanks of packaging material preferably of the type having a flat folded tubular structure comprising a support wheel provided with a continuous rotary movement bearing one or a plurality of angularly uniformly spaced articulated systems which project peripherally. Each of these articulated systems has one of its opposite rods developing in a piecewise linear manner with the third rod articulated at an intermediate point of the section of this piecewise linear development which projects peripherally to the greatest extent. The articulations on the bridge of these opposite rods of the articulated system have a cam follower structure operating with a corresponding cam, suction member means for the take up of the blanks in individual sequence from the fixed store being provided at the free end of this section of the piecewise linear development which projects peripherally to the greatest extent.
