Abstract (en)
It is disclosed a vertical winding apparatus for the packaging of pallet loads progressing sequentially along a transport path (Y-Y), to a packaging station (X-X) arranged transversally to said transport path (Y-Y). The apparatus comprises two carts (TR, TR') for supporting a respective group of vertical-axis reels (B1 .. Bn; B1' .. Bn') of plastic film (5) of different quality/heights, said carts (TR, TR') being arranged at the two sides of the transport path (Y-Y) and being apt to carry a pair of reels of equal quality/height (B1, B1' ; . . . ; Bn, Bn'), according to choice, in correspondence of said packaging station (X-X), as well as a pair of carrying means (P) arranged in said packaging station (X-X) and each one moving from a position next to one of said support carts (TR, TR') to a central welding position and vice versa, each one of said carrying means (P) being apt to accompany in said movement one edge of the film (5) of said pair of reels (B1, B1' ; . . . ; Bn, Bn'), and it furthermore comprises, associated with each reel: - a gripper (S) for the drawing of said edge of the film (5) carried by the reel (B1, B1' ; . . . ; Bn, Bn'), said gripper (S) being capable of being connected to and released from said carrying means (P), - guiding and detecting means (3, 3a, 4, 6) of said film (5), comprising at least one dancer roll means (3) moving under the action of the tension in said film (5) against the action of elastic means, and - a tensioning assembly (6, 7, 8, 9) comprising a roll driven in rotation acting on the periphery of said reel (B1, B1' ; . . . ; Bn, Bn'), the action of which can be modulated and controlled according to the position taken up by said dancer roll (3).
