Document Type and Number:
Japanese Patent JP2529841
Kind Code:
B2
Abstract:
Described is a drive for injection mould parts of a synthetic plastics injection moulding apparatus for injecting a wall part on a paper web, with at least one supply injector fixed on a carrier, a plurality of injector heads rigidly connected thereto and with driven connecting levers. So that parallel webs of a packaging tube can be passed more closely beside one another so that it is possible to manage with a few plasticizing units in the smallest space and with short flow paths for the synthetic plastics material, it is according to the invention envisaged that the direction of conveyance of the paper web extend at a right-angle to the direction of opening and direction of closure of the mould parts, a plurality of pairs of movable mould parts being disposed adjacent one another at a distance in the opening and closing directions, the connecting levers which take the form of ties and knee levers being so articulated that during injection, the forces which arise are mutually reinforcing and the carrier can be of lighter weight construction, at least in its middle portion.
