Abstract
A method and apparatus for opening an outer wrapping (11) of a reel (10) of, in particular, packaging material For the provision of a reel (10) of, for example, packaging material, such as paper, tinfoil or the like, it is necessary to remove an outer wrapping (11). The latter usually consists of an outer wound layer of the material. To open the wrapping (11), a material strip, namely an opening strip (32) is torn out of the wrapping (11). For this purpose, a tear-off member, namely a tear-off band (35), is placed with strong adhesion against the outside of the reel (10), On account of the relative movement, the opening strip (32) is torn out of the wrapping (11).
Claims5
Apparatus for preparing reels (10) made of axially directed webs of tearable packaging material, by opening a closed outer wrapping (11), characterized by the following features:
- a) attaching an opening assembly (31) to the outer wrapping (11) of the reel (10),
- b) providing the opening assembly (31) with a tear-off band (35), which grips the outer wrapping (11) by means of adhesive bonding to its outer side and including an opening strip (32),
- c) the tear-off band (35) extends across the wrapping (11) transverse there to,
- d) the tear-off band being movable in a direction parallel to the axis of the reel (10) or transverse to the wrapping (11) while maintaining the adhesive bond to the wrapping (11) by starting at one edge of the latter and moving to the opposite edge, for separating the opening strip (32) from the wrapping (11) due to the adhesive bond.
