Abstract

1493855 Shaping packages ALTSTADTER VERPACKUNGS VERTRIEBS GmbH 3 March 1975 [2 March 1974] 8766/75 Heading B8C Apparatus for shaping filled packets 5 made from tubing sealed longitudinally and transversely comprises a forming station having a rest plate 6 laterally moved members 8, 9, an abutment member 7 movable parallel to the plate and a vertically movable forming member 1 including pressure fingers 12 to engage and support the front of the packet against the pressure on the packet exerted by other parts of the forming member as it moves down. A filled packet is moved on to plate 6 by member 7 moving parallel to the plate 6 until its upper closure seam 53 engages an inclined surface 11 of a guide 10 on which the forming member 1 moves. The members 8, 9 are moved against the packet and member 1 is moved downwards to a position in which the pivotally mounted fingers 12 engage between the packet 5 and a previously shaped packet 4. As the forming member moves down, the seam 53 slides through a slot 26 in a centred hollow and is bent over a leaf spring 30 (Fig. 7). When movement of the member 1 is completed, hooks 19 extend through the fingers 12 to engage the package prior to moving it away from the shaping station. The hooks also push the spring loaded member 22 in the direction B causing the plate 28 to move over the seam 53 and press it flat.
