Automatic dispenser and positioner of non-preformed edge protectors made of cardboard or other flexible materials on the upper edges of packs that are to be strapped

摘要

The automatic dispenser and positioner of non-preformed edge protectors made of flexible material solves the very familiar problem in the industry of how to package packs or pallets with strapping and protect the material to be strapped against being cut into by the strap, and the opposite problem of how to protect plastic straps from being cut into by hard cutting edges of the pack being bound. The dispenser and positioner takes sheets of board or other flexible material from two vertical containers by means of two mechanical arms fitted with air vacuum suckers; the mechanical arms present the two sheets to a positioning mechanism also fitted with air vacuum suckers which positions them on the upper edges of the packs at the strapping points. The strap, output by a strapping machine co-ordinated with the dispenser and positioner, folds the sheets of flexible material into a right angle when tension is applied to it, causing it to mould around the edges of the pack. Operation is completely automatic and independent of the dimensions and position of the pack to be bound. IMAGE
