A cutter rotatably drivable about a rotational axis for cutting articles including printed products and lengths of flexible materials including paper, plastic, fabric, leather, and metal, includes a drive shaft; a circular knife holder which has a hub, which is removably connected to the drive shaft, and which has defined therein a plurality of guide grooves having a dovetail shape; a plurality of knives which are adjustably positioned within respective guide grooves, which are distributed across the circular knife holder, which have a clamping cross section that is movable within the guide grooves and is locked in place, which project beyond the circumference of the circular knife holder, and which have respective knife ends projecting beyond the circumference of the knife holder and forming a cutting plane that is perpendicular to the rotational axis of the cutter; and a clamping arrangement which extends conically from the hub to the circumference of the circular knife holder, which includes a clamping plate positioned between pairs of adjacent knives, which fastens each respective pair of adjacent knives to one another and to the knife holder in tightenable engagement.
摘要:
An apparatus for perfect binding of unbound print products to form bound print products comprises at least one processing station arranged along a circulating path between a feed station for the unbound print products and a delivery station for the bound print products, and a plurality of clamping devices arranged successively along the circulating path and driven jointly. Each of the clamping devices is adapted to hold at least two of the unbound print products such that the unbound print products face the processing station with overhangs that freely project from the clamping device and form spines of the unbound print products.
摘要:
A method for producing perfect-bound book blocks for books or similar printed products, including driving successively arranged clamps to circulate along an endless path of a perfect binding apparatus, positioning loose book blocks composed of gathered printed sheets inside conveying units of a conveying device, supplying the book blocks upon or prior to reaching the transfer region below the endless path to the clamps of the perfect binding apparatus, the supplying including inserting the book blocks into the clamps pivoted by approximately 90° around a perpendicular axis from a processing position for the book blocks and clamping the book blocks in the clamps with spines facing downwards, and transporting the clamped book blocks in an upright position for further processing in the perfect binding apparatus. An arrangement for producing perfect-bound book blocks is also provided.
摘要:
A method and apparatus for producing a digitally printed product that includes at least one section of sequentially printed sheets folded approximately in the center. The sequentially printed sheets are conveyed one after another on a conveying device and folded inside a folding apparatus to form a first fold. The folded sheets are gathered in a gathering station to form a section which is fed to a work station where the section is folded approximately in the center to form a second fold.
摘要:
To form stacks of printed products such as books, magazines, newspapers, brochures, etc., a plurality of printed sheets is delivered by a conveying section and assembled thereon into preliminary products, which are then formed into stacks, where the process for collating the printed sheets into preliminary products is controlled as a function of the size of the stack of printed products to be formed. A device for implementing the process includes a collating device for forming preliminary products and an indirectly downstream stacking device connected to a control unit.
摘要:
An arrangement and method for producing an adhesive-bound, printed item composed of a number of printed products. A circulating conveyor includes a conveying track and a plurality of space-apart conveying units driven along the conveying track, wherein along a first conveying section of the circulating conveying printed products are gathered into loose book blocks in the conveying units which are positioned transverse to the conveying direction and in a reclined position that is inclined counter to the conveying direction. The circulating conveyor includes an additional conveying section to which the book blocks are supplied from the first conveying section for being conveyed to an adhesive binder. The additional conveying section is operative to accelerate the conveying units so that a divisional spacing between the book blocks is increased, and to pivot the conveying units so that the book blocks are moved to an upright position.
摘要:
An apparatus for the processing of folded printed sheets is provided with at least one work station located next to a conveying path, with the work station preferably being a feeder for separating and opening the printed sheets. A plurality of support means is arranged sequentially on conveying means configured as a continuous loop, with the printed sheets in the region of the fold slidingly supportable on a respective support edge of the respective support means. The support means are spaced apart and sequentially guided past the work station and are inclined with respect to the conveying direction of the conveying means at least in the region of a work station.

A plurality of conveying elements is arranged on a traction device of a conveying arrangement in spaced apart succession in a conveying direction. Each conveying element includes a support surface and an end stop coupled to a front of the support surface, positioned perpendicular to the support surface and transverse to the conveying direction. The conveying elements are guided at least while in a feed region of respective feed devices that feed printed sheets to the conveying elements. The support surfaces of the conveying elements are aligned parallel to the conveying direction on the feed section. A holding down device located at a downstream end in the conveying direction of the feed region of each of the feed devices holds down and guides the book block from above while conveyed on the conveying element.
