Device having a rotational element for forming sleeve-like foil envelopes

摘要

The invention relates to a device 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 for making a cut in this strip of sleeve-like foil material 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 from the device. The device of the invention is characterized in that the device comprises rotational element means (20′) arranged for imparting a rotary motion during operation to the sleeve-like envelope to be discharged from the device. By imparting a rotary motion to an individually formed sleeve-like foil envelope while it is being discharged from the device it is achieved that the foil envelope will remain open, making it possible to place the envelope round a container in a simple and effective manner.

主权项

1. A device for forming sleeve-like foil envelopes from a continuous flat strip of a sleeve-like foil material, the device comprising:
a supply element 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 so as to form and separate individual sleeve-like foil envelopes from the strip of sleeve-like foil material; a rotation mechanism having an axis of rotation and disposed at a location downstream from the cutting member and in the path of the separate individual sleeve-like foil envelopes such that the rotation mechanism rotates about the axis of rotation to physically contact and concurrently impart both a rotary motion to the individual sleeve-like envelopes and a translation motion to said sleeve-like envelopes for discharging the individual sleeve-like foil envelopes from the device.
