Device for forming sleeve-like foil envelopes from a continuous flat strip of a sleeve-like foil material

摘要

The invention relates to a device (10) for forming sleeve-like foil envelopes from a continuous flat strip of a sleeve-like foil material, comprising supply means (12) for supplying the continuous flat strip of sleeve-like foil material (1), cutting means (14-15) for making a cut in this strip of sleeve-like foil material (1) over the full width thereof so as to obtain the individual sleeve-like foil envelopes, as well as discharge means (20a,20b) for discharging the individual sleeve-like foil envelopes (1') from the device. According to the invention, the device is characterised in that the cutting means comprise at least two cutting elements (14-15) that are movable relative to the flat strip of sleeve-like foil material, each cutting element comprising at least one cutting blade (15',15') extending parallel to at least part of the width of the strip, in such a manner that the individual cutting blades of the cutting elements form several partial cuts contiguous to each other in the strip of sleeve-like foil material over the entire width thereof in successive cutting operations.
