Roll film etc. transport

An insertion strap or sleeve (1, 2) contains a reversible fixer (4a, 4b) and/or a reversible fixer outside each insertion hole. The fixer is longitudinal and off-parallel and also off-normal relative to the insertion direction. Two flexible bands (1, 2) of different thickness joined at points (3) form two straps. One band (1) has a reversibly deformable fixer (4a) in its upper bow and the other band (2) contains, and is deformed in the part narrower than the first band (1), by the inserted roll film (5). The second band (2) also mounts an undeformed fixer (4b). This fixer and one at the far end of the strap lie outside the insertion hole. The deformation of the three fixers (4a) caused by the insertion of the roll film is shown by the inclined lines depicted. OF DLRAWING - The drawing shows the film holder inside and plan view.
