Abstract
Glue roller for use in labeling machines and the like, comprising a metal hub, a tubelike support body fixed on the hub, and an elastic sleeve with a cylindrical outer surface seated on the support body. The support body is a first moulded part of foam material having sealed boundary zones, which is foamed directly onto the hub. The elastic sleeve is a second moulded part of elastic foam material with sealed boundary zones, which is foamed directly onto the support body. The support body and elastic sleeve are provided with interengaging projections and recesses which extend parallel to the axis of the roller.

Glue roller for labeling machines, with a metal hub for rotationally fixed mounting on a drive shaft, a tubelike support body fixed on the hub and with an elastic sleeve, having a cylindrical outer surface, seated on the support body, the hub and the support body being provided with interengaging recesses and projections, characterized in that the support body (6) is formed by a first moulded part of foam material having sealed boundary zones, which is foamed directly onto the hub (1), that the elastic sleeve (11) is formed by a second moulded part of elastic foam material with sealed boundary zones (13), which is foamed directly on the support body (6), that the foam material of the support body (6) has a lower elasticity than the foam material of the sleeve (11), and that the support body (6) and the elastic sleeve (11) are provided with interengaging projections (10) and recesses (12) which extend parallel to the axis of the roller.
A glue roller assembly for use in labeling machines and the like, said roller assembly comprising:
- an elongated generally cylindrical hub (1) for being rotated about its longitudinal axis,
- a first layer (6) of foam material having a predetermined hardness molded onto the outer surface of said hub, said first layer having an inner surface interfacing with said hub and a nonporous outer surface having axially spaced apart ends,
- a second layer (11) of elastic foam material having lesser hardness than said first layer molded onto said outer surface of said first layer, said second layer having an outer surface and having an inner surface interfacing with said outer surface of the first layer,
- said interfacing surfaces of said second layer and first layer being provided with interengaging projections (10) and recesses (12) which extend parallel to the axis of the roller.
