Abstract: Covering of raw boxes with a sheet blank in a box laminating machine with a rubbing-down device that sweeps or rolls over the surface to be covered and a counter-holder that interacts with said rubbing-down device, wherein the rubbing-down operation takes place during a transport movement of the box and the counter-holder plunges into the box in order to support the wall to be covered against the rubbing-down device.

Abstract: A box laminating machine with two rubbing-down devices that lie opposite of one another with respect to the box to be covered, wherein each rubbing-down device has a counter-holder that plunges into the box and a rubbing-down element that sweeps over the wall to be covered, which is supported against the counter-holder. The rubbing-down operation of opposing walls takes place successively, wherein a movement of the box relative to the counter-holder takes place perpendicular to the wall to be rubbed down.

Abstract: The invention pertains to a device and a method for producing hollow bodies that are open on one side of predominantly plane material blanks by erecting and gluing their sides along prepared bending edges, wherein said device features a shaft that is arranged directly downstream of the erecting elements and accommodates the hollow bodies in order to cure the glued joints, and wherein the products are spaced apart from one another during their transport within the shaft. The transport device provided for this purpose preferably acts directly upon the glued edges or areas located adjacent thereto such that the glued joint is continuously stabilized during the curing process.

Abstract: A device for centrally splitting book blocks (1) in bookbinding machines, wherein the book blocks (1) being transported forward of a conveyor (2) are split by being pushed against a splitting element (3). In order to also ensure the functionally reliable splitting of book blocks (1) that consist of thick cardboard sheets or panels, a blunt wedge (10) in the form of a gable roof acts upon the front edge cut (1a) of the book block upstream of the splitting element (3) and produces a gap that begins in the leading book block edge and extends into the head edge cut or the foot edge cut (1b) and into the front edge cut (1a). The splitting tool (4) penetrates into the book block (1) through the gap. In one preferred embodiment, a spring-loaded, rotatable wedge roller (10) is used that has a rounded point and a wedge angle (a) of 130°.
