Abstract

Bags are reinforced around the handles by aligning a continuous flattened tubular film with a strip of reinforcing material perpendicular to one edge of the tubing, spreading and covering one edge of the tubing with the reinforcing material with sufficient overlap on to the broad faces that subsequent tucking in and flattening of the edge produces an 'M' profile reinforced zone which can be slit along the centre to form two reinforced edges for bags to be made by subsequent transverse welding and cutting of the tubular stock. Pref. hand holes are subsequently punched in the reinforced zones. Pref. the longitudinal slitting is by a rotary knife. Suitable for mfr. of e.g. carrier bags of polyethylene films reinforced with polyethylene strip. Simple continuous introduction of reinforcement allows high bag mfg. throughput rates.
