ABSTRACT:
A gusset forming machine includes a mandrel having a support surface on which a blank for the gusset is manually mounted, and one or more pusher assemblies which are driven into contact with the mandrel to deform the blank, thus forming a gusset. Preferably, each pusher assembly includes a holding blade which prevents movement of the blank relatively to the mandrel during the gusset forming operation, and a plurality of pushing blades which deform the blank into valleys formed between adjacent ridges formed on the support surface of the mandrel, thus forming the gusset. The mandrel is preferably movable into and out of alignment with the pusher assembly or assemblies. Multiple pusher assemblies are preferably provided which extend at angles from one another and produce a multi-sided gusset in a single operation.
