Abstract: A device for forming envelopes from a continuous flat strip of a sleeve-like foil material, comprising a supply member, a cutting member for making a cut over the full width of the material so as to provide individual envelopes, and a discharge member for discharging the envelopes. The cutting member comprises at least two cutting elements movable relative to the strip of material, each cutting element comprising at least one cutting blade extending parallel to the width of the strip, such that the individual cutting blades form several partial cuts contiguous to each other in the foil material over the width thereof in successive cutting operations.

Abstract: The invention relates to a device for forming sleeve-like foil envelopes from a continuous flat strip of a sleeve-like foil material, comprising a supply member for supplying the continuous flat strip of sleeve-like foil material, a cutting member for making a cut in the strip of sleeve-like foil material over the full width thereof so as to provide the individual sleeve-like foil envelopes, as well as a discharge member for discharging the individual sleeve-like foil envelopes from the device. The device is characterized in that the cutting member comprises at least two cutting elements that are movable relative to the flat strip of sleeve-like foil material, each cutting element comprising at least one cutting blade 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.
