A roller for transferring labels

Abstract

An aspirating roller (1) for transferring labels, comprising at least a pair of pads (20;21) projecting relative to a lateral surface (1a) of the roller (1). The roller (1) is characterised in that at least a portion of the lateral surface (1a) of the roller (1) present between the pads (20;21) is elastically deformable. A method for removing / mounting an elastically deformable plate-like element (6), of the type present between a pair of pads (20;21) and defining a lateral surface (1a) of a roller (1) for transferring labels.

Description

technical field [0001] The present invention relates to an aspirating type roll for conveying labels, the roll comprising at least one pair of pads projecting relative to the sides of the roll, and a method associated therewith. Background technique [0002] Rolls for conveying labels are known for use on labeling machines in which a label film is unwound from a reel and conveyed to a cutting device which cuts it to form labels for gluing to a container. [0003] The labels thus formed tend to be substantially rectangular or square in profile with two vertical and parallel edges. [0004] The transfer rollers, rotating at a predetermined speed about a generally vertical axis, pick up the labels and transfer them to the corresponding gluing unit and then to the container for labeling. [0005] In particular, the gluing device applies a first strip of glue along the rear side of the first vertical edge of the label followed by a second strip of glue on the second vertical edg...

AI Technical Summary

Problems solved by technology

[0015] Glass containers, which often have tight dimensional tolerances, considerably complicate the installation as well as the correct calibration of the labeling machine, often violently in contact with the conveyor rollers

[0016] Therefore, since glass is a hard but extremely fragile material, the inevitable breakage of the container inevitably spills the liquid and shuts down the machinery for cleaning and repairs, which results in a drastic reduction in the productivity of the plant

[0017] In PET containers, this problem is not encountered because, although there is contact between the container and the side of the roll, the container itself is absorbable and deformable, and the forces exerted at the point of contact are relieved
