Abstract
Packs formed from a group of sacks bound by straps for feeding to so-called sack applicators are conveyed continuously in succession by a particular arrangement of endless driven belts, comprising a belt acting on the lower central part of the pack and a central upper belt and two lateral belts or shoes acting on the upper side parts of the pack to result in transverse arching of the pack and the insertion of a fixed reference member between the pack and strap to bring the strap into contact with a rotary cutter for its cutting. The hanging cut part of the strap is led between cooperating inclined rollers which remove the strap.
