Abstract

A head for a horizontal flow wrapper packaging machine for forming a bandolier of product packages. The head includes a rotatable first shaft having a plurality of knife elements each including a blade and first and second upper crimping elements. The head also includes a rotatable second shaft having a plurality of anvil elements. A rotation speed of the second shaft is independent of the rotation speed of the first shaft. Each anvil element includes perforation and cutting surfaces and first and second lower crimping elements. A rotation speed of either the first shaft or second shaft is changed to move either a knife element or an anvil element, respectively, between a perforation position and a cutting position. The first upper and first lower crimping elements and the second upper and second lower crimping elements also mate to crimp the packaging material in either the perforating or cutting positions.
