  • Patent number: 4912905
    Abstract: The invention relates to a contact pressure element for metal foil blanks laid around the neck and top of bottles (3) in a labelling machine. Retained by a retaining ring (5) in front of the opening of a casing (1) having a bell-shaped inner wall (7) is a resilient plate (2) whose front side facing the end face of the bottle (3) is made of an open-pored resilient foamed plastics, the rear side of the plate (2) being constructed with closed pores and its peripheral edge being formed with an annular bead (8). When the contact pressure element makes an axial movement towards the end face of the bottle (3), the plate (2) yields to the axial pressure, its rear side rolling down the bell-shaped inner wall (7) in the zone of the annular bead (8), so that the front side of the plate (2) is brought into radial contact pressure with the side of the bottle top in the zone of the annular bead (8). Such contact pressure is produced without folding the plate (2) and substantially without warping.
