Abstract: A pack for containing materials which are capable of flow includes a tube formed by a longitudinal sealing seam, along with a bottom and a cover closing the tube ends. The cover is formed from thermoplastic material without a carrier material, is injected on the tube, and has a pouring spout. The tube comprises cardboard which is coated with thermoplastic material on one side. The bottom is quadrangular, formed from the folded-over tube of the pack of a fold-type closure. The cover and the cross-section of the pack, at least in the region of the cover, are round. To improve such a pack with a handle so that the final consumer enjoys improved handleability and transportability, the invention provides that a portion of the tube wall, which adjoins the periphery of the cover, is folded onto itself, forming a handle, and is joined to provide a double-wall surface portion in which a gripping opening is provided. The cover is extended over the upper edge of the double-wall surface portion with the gripping opening to provide a stiffening web.

Abstract: The proposed cross transfer device has two parallel support tubes (2a, 2b) which are displaceable in reciprocating manner in the workpiece transfer direction in the forming area and to which are fixed in each case an upper and a lower gripper box (3a, 3b). The two gripper boxes are used for the rectilinear guidance of gripper jaws (11) which interact in pairs, seize a workpiece at each forming station (U1 to U3) and can be transferred to the in each case adjacent forming station (U2 to U4) and released again. Transmission levers (6a, 6b) pivotably mounted in the gripper boxes (3a, 3b) are used for driving the gripper jaws (11), the pivoting movement of which transmission levers (6a, 6b) is controlled by a rotating camshaft (4a, 4b) which in each case is centrally mounted in one of the support tubes (2a, 2b) via antifriction bearings (15) and supporting pins ( 14). The cam members (5) of this camshaft are fan-type disks (5a, 5b) which can be adjusted in each case relative to the axis of rotation of the camshaft supporting it and relative to one another, so that each transmission lever (6a, 6b) can be individually set, independently of the further transmission levers provided, for controlling a certain gripper movement.
