Abstract: The invention comprises a conveyor device 1, provided with a turning station (3) and a supply belt for supplying products to the turning station in a direction of conveyance with a first orientation. The turning station comprises a cam belt (20) that is rotatable in a closed loop and has cams (28) placed at regular intervals, and also a retaining element (26), for retaining products during the transition from the first track part (24) to the second track part (25). The cams on the belt (20) and the retaining element (26) ensure that at high speeds the products are positioned in an accurate manner during the change of direction. The invention also relates to a motor suspension (30). A drive motor (33) and a drive roller for a conveyor belt are suspended from two arms. With the motor suspension, the belt tension and belt orientation can be adjusted in a simple manner, and the motor can be removed in a simple manner for repair or replacement.

Abstract: The invention relates to a rotatable gripper device (1) for picking up and rotating products which are supplied on a conveyor belt. The device according to the invention comprises a gripper head (2, 3) which can rotate about a vertical central shaft (4) and has a gripping member (18) which can rotate about its axis. For upward and downward movement, the device comprises a first cam roller (6, 7) and cam discs (8), and for rotation about the axis comprises a second cam roller (9, 10) and cam disc (11). The device according to the invention is of a simple and relatively lightweight design, so that it is suitable for operating at high speeds. The gripper device according to the invention can be used to accurately set the rotational path of the gripping member (18) at the gripping position and the release position, by means of the shape of the cam disc, in order to produce a gradual transfer.

Abstract: A packaging machine for making flow packs, which is provided with closure elements for making transverse seams in a packaging material which has been formed into a tube, and with cutting devices for then making cuts in the transverse seams. The cutting devices are arranged on the circumference of a pair of cutting rolls which, in their circumferential direction, are moreover provided with gripper elements for manipulating the flow packs.

Abstract: The invention relates to a conveyor device for accelerating a series of products. The conveyor device includes a feed device for supplying products at a feed velocity along a transport path in the direction of transport T.sub.1. By operating an acceleration device located downstream of the feed device, the products are lifted up and transferred to a transfer device, which delivers the product downstream at regular intervals and at a higher velocity. The feed device includes a stationary take-over plate, and the acceleration device includes grippers which move along a hypocycloid path. In this case, the grippers preferably move along an essentially triangular path with a path section situated parallel to the direction of transport. By way of the grippers, the product which has been placed on the take-over plate is lifted up at a low initial velocity and is then accelerated in the direction of transport.

Abstract: A conveyor device for accelerating a series of products comprises a feed device for supplying products at a feed velocity, an acceleration device which is positioned downstream thereof, and a transfer device for taking up the accelerated products and delivering the products at regular intervals and at an accelerated velocity. The acceleration device comprises a transport path, with a belt of projections on either side thereof, which belt rotates at a lower velocity than the transport path. The transport path carries along the products at an accelerated velocity until they bear against the projections. After they have come to bear against the projections, the accelerated products are taken up by the transfer device. Due to the fact that the position of the projections is known at all times, an accurately determined position of the accelerated products is obtained in this way and shifts of the products which have occurred during acceleration are compensated for.

Abstract: Flowpacker with unilaterally supported cross sealing shafts, on which one or more cross seal tools are disposed, distributed over the radial periphery. For rapid resetting and simple maintenance, the cross seal tools are disposed on a casing part, which casing part is pushed onto the cross seal shaft, and is retained thereon. The casing part is, for example, held clamped on all sides on the cross seal shaft.

Abstract: Method for arranging a series of products (17, 106) which are moving in succession in the downstream direction along a conveyor belt (2, 103, 104), in such a way that they go into phase with a processing unit connected downstream. To control an activation element for arranging the products, before a product passes the element, the first speed Vx of the products upstream and the second speed Vy downstream of the element, the position Yn of the product processing unit, and the position Z of the element are measured. The distance Xn which is covered by the detected product from the above-mentioned position is determined. The required position Za of the element (9, 113) and the required speed Vya are calculated from Vx, Vy, Xn and Yn. The measured position Z and the measured second speed Vy are compared with the required position Za and the required position Za or the measured speed Vy and the required speed Vya, the element is moved or the second speed Vy is changed.

Abstract: Stacking device for stacking groups of articles on top of each other, the articles being supplied to that stacking device in a single stream and at a common first level, the device comprising moveable elements which are substantially parallel to the article track, and which are adapted to receive one or more articles each time, and which are designed to move through a first track section and a second downstream track section, wherein in said first track section, articles are to be received and in said second track section, the articles are to be delivered at a subsequent level different to that of said first level, and means, in or beyond the second track section viewed in downstream direction, for positioning a group of articles, successively located at various levels, substantially on top of each other, wherein each time the level of the elements in said first and second track part is substantially the same.
