Suction hole arrays in which a plurality of suction holes which suck the label are aligned in a line are formed on the surfaces facing one another of the first suction rods and the second suction rods. The suction holes are arranged in such a manner that the suction hole arrays of the first suction rods and the suction hole arrays formed in the second suction rods opposing the first suction rods are at least partially nonparallel.

Abstract: The invention relates to a mandrel, a sleeving device and a method for sleeving containers. The mandrel is suspended in the sleeving device. The mandrel opens a foil to form sleeves. The foil is fed around the tubular outer surface of the mandrel. According to the invention the outer surface of the mandrel is formed by at least two separate mandrel bodies. At least one of the mandrel body is biased outwardly to increase the circumference of the outer surface. This circumference is automatically adapted to the current, instantaneous circumference of the foil fed around the mandrel.

The apparatus includes a sleeve orientation unit that uses a moveable support surface to hold and rotate the sleeve relative to the container. To that end, the apparatus further includes a determining unit for determining an angular position difference between the container and the sleeve relative to an axis perpendicular to the conveyor belt on which the container is transported. The angular position difference is used to control the movement of the support surface.

Abstract: The present invention includes: a label opening unit, which preliminarily opens a tubular label folded in a sheet; a label expansion unit, which expands the preliminarily opened label; a bottle lifting unit having a mounting, on which the bottle is mounted and which can rise and fall; and a bottle pull-up unit, which lifts the bottle while holding with the bottle an upper end portion of the label attached to the bottle. After the bottle lifting unit has lifted the mounting on which the bottle is mounted, thereby inserting the bottle into the label expanded by the label expansion unit, the bottle pull-up unit pulls up the bottle, thereby removing expansion claws from the label and moving the bottle to above clamp members of the label opening unit.

Abstract: A film-fitting device includes a cutting mechanism that cuts a label-forming medium into a predetermined length, a film transfer mechanism that transfers downstream a tubular film arranged around a mandrel, and a shot roller that receives the tubular film transferred by the film transfer mechanism and delivers the tubular film downstream while rotating the tubular film in the circumferential direction. The distance from the cutting mechanism to the shot roller and the distance from the film transfer mechanism to the shot roller are both greater than the length of the tubular film formed by the cutting. Further, rotational drive of the shot roller is carried out by an independent servo motor or stepping motor.

Abstract: The invention relates to a method, a sleeving device and a mandrel for arranging sleeves around products such as containers. Foil is opened on the mandrel and fed over the outer surface of the mandrel. The foil is cut at a first position to form individual sleeves of predetermined length. Sleeves are discharged in axial direction from the mandrel over the product. The sleeves are discharged by engaging the sleeves at a second position. The circumference of the outer surface of the mandrel near the second position is smaller than the circumference of the outer surface of the mandrel upstream from the first position.
