Abstract
An apparatus is disclosed for feeding lengths of a thin web (F) which is provided particularly in a machine for packaging articles into a heat-contractible thin web, and in which the cutting of the thin web (F) is made by the blade (260) of a rotary blade means (60) carried by the means (58, 59, 70, 69, 68) for lifting and lowering the rotary blade means, preferably by a swingable system. The rotary blade means (60) is continuously driven in rotation, and the same is cyclically lowered and caused to cooperate by its blade (260) with a stationary counterblade (34), whereby a cut is made in the thin web (F) lying therebetween, and the said rotary blade means is then lifted and kept in its uplifted position, until a required length of the thin web (F) has been caused to pass thereunder. The length of the thin web (F) is adjustable by changing the speed at which the thin web is caused to slide through the cutting unit, and/or by changing the frequency at which the rotary blade means (60) is lifted and lowered.
