Abstract: Device for conveying a series of spaced apart articles to a processing machine, in particular these articles being formed to groups of a specific number comprising a drivable conveyor belt system with a run running essentially horizontally which can accommodate the series of articles, and which runs parallel to and at a distance from an endless chain on which a number of equally spaced drivers are mounted the drivers being movably mounted in such a way that they are placed only after passing a control element in a position projecting relative to of the conveyor belt system between articles lying thereon, which control element is fitted so that it can move to and fro over at least a portion of the run of the endless chain parallel thereto and is coupled to a first device which can give a signal for each passing or incoming article, and near the downstream end of the chain a fixed second device is present which for every passing group of articles can give a multiple "p" of these signals, so that these signals a

Abstract: An apparatus for packing articles having at least two sealing rollers mounted for rotation by a mechanism so that the rollers are rotated with a non-constant rotational velocity. The mechanism comprises a crank arm and a coupling member, and a driving cam is provided which is shiftable in a slot formed in a follower member extending parallel to the crank arm. The design is such that every time the axis of rotation of the crank arm has moved along a complete circular path the crank arm is rotated at least one time over 360.degree..

Abstract: A method for splicing the trailing end portion of an advancing web of packing material to the leading end portion of an initially stationary second web of the same packing material such that after splicing marks provided on each of the webs in an equally spaced relation continue as an uninterrupted regular row, in particular in a packing machine. The articles to be packed are advanced spaced apart as a continuous flow into a web of packing material folded to a tube and are carried and advanced along sealing stations by the advancing tube for producing a longitudinal sealing seam and transverse sealing seams in the packing material between the articles. The transverse seams are cut thereafter and the discrete packed articles are discharged on a coveyor, in which the first web runs over a roller and the leading end portion provided with an adhesive of the second web is placed over a second roller opposite to the first roller.

Abstract: A number of elongated pressure members are located in recesses in the shaft, to be displaced axially and radially outwards by means of pressurized fluid until they engage against the inside of the reel. Within the pressure members an actuating sleeve is mounted for reciprocating movement between extreme end positions, and having wedge surfaces cooperating with wedge surfaces formed on the pressure members. Two spaces are defined in the shaft communicating with each other through a relatively narrow channel and closed by a first valve member in one position. The first space communicates directly with the source of pressurized fluid. The second space is bounded by a surface of the actuating sleeve and is provided with a second normally closed valve member.

Abstract: A device for pushing objects lying end to end on an endless conveyor from the conveyor one at a time, including two parallel discs arranged on top of each other and with axes of rotation spaced apart in a vertical plane. A number of pins situated at equal distances from each other being pivotally secured in the upper disc as equal distances from its center, with a second set of pins being connected to the lower disc at the same radial distance from its center and with connecting members connecting the lower ends of the first set of pins to the upper ends of the second set of pins. Each pin of the second set of pins carrying at its lower end a push plate having a length shorter than the length of the objects to be pushed off. The discs overlap the conveyor in such a manner that when the discs are rotated the push plates will brush over the conveyor over a distance at least equal to the width b of the objects, while the radial distance between each pin and the center of the discs exceeds (4b.sup.2 +1.sup.2)/8b.

Abstract: Apparatus for positioning articles fed in a continuous closed row between the carriers of a drag conveyor, comprising a first conveyor belt receiving the articles at one end, a second in-line conveyor belt movable at a higher speed than the first conveyor belt and arranged to transfer the articles to the drag conveyor, and an orbiting stop at the transition point between the first and second conveyor belts synchronized with respect to the movement of the drag conveyor whose path comprises a portion essentially parallel to the first conveyor belt in the direction of travel, a portion directed backwards and away from the conveyor belt, and a portion directed again towards the conveyor belt.

Abstract: Apparatus for positioning articles which are continuously fed by a conveyor belt in a closed row between the carriers of a drag conveyor, comprising equally spaced apart blades movable in a vertical, endless path located above and in the proximity of the discharge end of the conveyor belt. The blades are arranged such that in travelling along the lower path portion they are capable of entering between the articles in engaging relationship. A device is provided for accelerating the leading article with a blade being positioned between the article and the next article at its rear.
