Abstract:
1. Sleeving device for arranging sleeves of a predetermined sleeve length around products, such as containers, the sleeving device comprising: a frame, suspended to the frame, a mandrel configured to open the foil to form a sleeve, the mandrel having a substantially tubular outer surface around which foil is fed, the mandrel extending in an axial direction, at least one feed unit configured to feed the foil to the mandrel, at least a conveyor configured to transport products, such as containers, and to align products with the axial direction of the mandrel, at least one cutting device configured to cut the foil fed around the mandrel at a blade clearance located at a first position to form individual sleeves having the predetermined sleeve length, and at least one sleeve discharge unit configured to discharge sleeves in the axial direction from the mandrel over the product, the sleeve discharge unit engaging the individual sleeve at a second position, wherein the sleeve discharge unit comprises a rotational sleeve discharge unit configured to impart a rotational movement to the sleeve around an axial axis, wherein a first portion of the outer surface of the mandrel upstream from the blade clearance has a first circumference, the first portion configured to position the foil radially, wherein a second portion of the outer surface of the mandrel downstream from the blade clearance has a second circumference that is smaller than the first circumference so as to form a foil wrinkling portion configured to allow twisting of the foil over a limited length of the foil, and wherein the circumference of the outer surface of the mandrel downstream from the second portion does not enlarge.
