Abstract
A packaging machine for inserting a batch of semi-compressible articles into preformed bags open at one end, having a longitudinal ram movable toward and away from the open bag and batch receiving means located at the leading end of the ram to carry the batch into the open bag, the batch receiving means having a pair of generally elongated flat parallel walls extending forwardly of the leading end of the ram and spaced from each other to receive the batch therebetween. At least one of said walls is flexible along its length and engages means located at the entrance of the bag by which it is deflected transversely of the direction of movement to impart a compressive force upon the articles as they are inserted into the bag.
Claims6
In a machine for packaging a batch of semi-compressible articles into preformed bags open at one end, apparatus for inserting said batch in said bags comprising a longitudinal ram movable toward and away from said open bag, batch receiving means located at the leading end of said ram to carry said batch into said open bag, said batch receiving means comprising a pair of generally elongated flat parallel walls extending forwardly of the leading end of said ram and spaced from each other to receive a plurality of articles forming a batch therebetween, at least one of said walls being flexible along its length, means located at the entrance of said bag to deflect said flexible wall transversely of the direction of movement so as to impart a compressive force upon the articles in said batch as they are inserted into said bag.
