Abstract: The invention relates to an apparatus by means of which sheet like products which follow one after the other along a feed section are transferred to a conveying arrangement with individually controllable grippers which can be moved in the conveying direction, are arranged one behind the other and are designed for gripping the products at their leading edge, the feed section having, in its end region which is directed toward the conveying arrangement, a conveying nip, in which the sheet-like products are retained, at least in part, on both sides, in the case of which apparatus, in the product-receiving region of the grippers, a positive stop, which is active during each product transfer, is provided for the leading edges of the products, the spacing between the positive stop and conveying nip being selected such that the trailing edges of the products are still located in the conveying nip when the leading edges strike against the positive stop.

Abstract: An apparatus and method are provided for gathering flat articles (5) into stacks (9) by conveying stacks in production successively along a gathering route (1) past feed stations. The stacks (9) are conveyed on stack supports (2) with supporting surfaces (7). Leading edges (5.1) of the articles (5) to be added to the stacks are held by holding elements (4) that move in a supply route (3) that traverses the gathering route (1) at the feed stations. Each article (5) is inserted between successive stacks (9) or stack supports (2), with the leading edge (5.1) being inserted first. The inserted article is released from its associated holding element (4) and then positioned on the upstream or downstream stack (9) or stack support (2) by the force of gravity and/or by its own inertia, and the holding element (4) is conveyed onwards in a downward direction.

Abstract: For the horizontal positioning of serially supplied, flat objects (1) to be conveyed onward, the objects (1) are supplied suspended, one of their main surfaces (10) facing downstream and the other main surface (11) facing upstream. Prior to positioning, lower edge zones (13) of the objects (1) are selectively accelerated or retarded relative to the upper edge zones (12), so that the objects (1) are brought into a position inclined relative to the vertical. Thereafter, the upper edge zones (12) are released and the objects (1), under the influence of gravity, are positioned on an onward conveying device, selectively either the downstream or the upstream main surface (10 or 11) facing upwards. For retarding or accelerating the lower edge zones (13), for example, a conveyor belt or two conveyor belts adjoining one another are utilized. The speed (v.3) of the conveyor belts is adjustable to convert from accelerating operation to retarding operation.

Abstract: Flat articles are taken over from a supply device supplying the products e.g. in the form of an imbricated stream and, for creating groups, are transferred to a conveying-away device. Thereby the supply direction and the conveying-away direction are angled in the horizontal plan view. For the transfer of the articles devices are used having a circulating conveying organ with laterally protruding gripper arms and grippers arranged on the gripper arms. The circulation track of the conveying organ extends in a take-over direction through a take-over zone and in a transfer direction through a transfer zone and represents a deflection between take-over and transfer zone.

Abstract: Flat articles (13) are taken over from a supply device supplying the products e.g. in the form of an imbricated stream (21) and, for creating groups, are transferred to a conveying-away device (1). Thereby the supply direction (Z) and the conveying-away direction (1) are angled in the horizontal plan view. For the transfer of the articles (13) it is suggested to use devices (20) comprising a circulating conveying organ (11) with laterally protruding gripper arms (10) and grippers (12) arranged on the gripper arms (10). The circulation track of the conveying organ (11) extends in a take-over direction (3) through a take-over zone (A) and in a transfer direction (2) through a transfer zone (C) and comprises a deflection (B) between take-over and transfer zone.

Abstract: Flat articles (5) are gathered into stacks (9) by conveying stacks in production successively along a gathering route (1) past feed stations and by adding one article to each stack in every feed station. The stacks (9) in production are conveyed on stack supports (2) with supporting surfaces (7). The supply direction of the articles comprises a component parallel to the stack conveyance direction and the supporting surfaces (7) are advantageously arranged not in parallel to the gathering route (1). The articles (5), each respectively gripped by a holding element (4) on one of their edges (5.1), are conveyed along a supply route (3) to the feed station. The supply route (3) traverses the gathering route (1) at the feed station. The articles (5) are inserted between successive stacks (9) or stack supports (2) respectively e.g. from above with their leading edges (5.1) held gripped.

Abstract: For the horizontal positioning of serially supplied, flat objects (1) to be conveyed onward, the objects (1) are supplied suspended, one of their main surfaces (10) facing downstream and the other main surface (11) facing upstream. Prior to positioning, lower edge zones (13) of the objects (1) are selectively accelerated or retarded relative to the upper edge zones (12), so that the objects (1) are brought into a position inclined relative to the vertical. Thereupon the upper edge zones (12) are released and the objects (1) with the assistance of the force of gravity are positioned on an onward conveying means, selectively either the downstream or the upstream main surface (10 or 11) facing upwards. For retarding, resp., accelerating the lower edge zones (13), for example, a conveyor belt or two conveyor belts adjoining one another is or are utilized, the speed (v.3) of the conveyor belts being adjustable for a conversion from accelerating operation to retarding operation.
