ABSTRACT:
Holding device for food in particular intended for use together with a load sensing cell in packing machines for food. The food is weighed before it is included in a package so that the price tag can be placed on a film (lid) already before this is sealed over the food. The holding device includes a suction means (1) and round this arranged contact pins (4). The contact pins are axially adjustable so that when the holding device is brought to contact with the food these adjust to the shape of the food. When or before a vacuum is fed to the suction means (1) a cylinder shaped rubber membrane (8) act on pistons (5) radially arranged that press against the contact pins (4) locking these from a movement. In this manner the food is firmly and ridgedly held, which in turn is necessary for the weighing of the product and secondly for enabling the replaceing of this without problems in identically the same position as it was removed from the bottom part of the package.
