A belt driving device includes an annular belt member, rotary members, a protrusion, and a removing member. The rotary members extend in parallel and rotate. The belt member is wound around the rotary members. The protrusion protrudes from an inner peripheral surface of the bel member. The protrusion extends along an edge of the belt member. The protrusion and each rotary member are arranged in an extending direction of the rotary member. The removing member includes a plate-shaped portion. The plate-shaped portion is in contact with an outer peripheral surface of the belt member at a location where the removing member faces one of the rotary members with the belt member being interposed therebetween, so as to remove unnecessary matters from the outer peripheral surface of the belt member. The removing member extends to an outside of end portions of the rotary members in the extending direction.

Disclosed is a conveying apparatus and method for conveying a tire layer, wherein the conveying apparatus includes a swivel conveyor with at least one endless belt or wire, a first pulley, a second pulley and a third pulley that define a minimal loop (L) for guiding the endless belt or wire along a conveying run and a return run, wherein the third pulley is arranged between the conveying run and the return run, and is swivable about a swivel axis (X) between a first swivel position and a second swivel position. The pivot position is chosen such that the length of the minimal loop when the third pulley is in the first swivel position is the same within a tolerance of less than 1 percent with respect to the length of the minimal loop when the third pulley is in the second swivel position.

A belt driving device includes an annular belt member, rotary members, a protrusion, and a contact member. The belt member includes first and second edges. The belt member is wound around the rotary members. The protrusion protrudes from an inner peripheral surface of the belt member. The protrusion and each rotary member are arranged in an extending direction of the rotary member. The protrusion is provided at the second edge. The contact member is closer to the first edge. When the belt member deviates, the contact member comes into contact with the belt member. A difference between a position of the belt member when the protrusion comes into contact with an end surface of one of the rotary members and a position of the belt member when the belt member comes into contact with the contact member is equal to or less than a width of the protrusion.

A post compression carton rejection system for receiving cartons in-line from a carton assembly system having a compression conveying section for compressing folded and glued cartons for delivery to a packing system. The post compression carton rejection system comprise a frame adapted to be supported between the compression conveying section and the packing system. An infeed conveyor is mounted to the frame and has an infeed belt for transporting folded and glued cartons from the compression conveying section and an infeed drive for driving the infeed belt. An outfeed conveyor is mounted to the frame between the infeed conveyor and a conveyor exit proximate the packer, in use, and comprises a nose extension conveyor having an outfeed belt including a dump gate controllably retractable at the conveyor exit to selectively dump folded and glued cartons, an outfeed drive for driving the outfeed belt and a dump gate actuator for opening and returning the dump gate. A controller operatively controls the infeed drive, the outfeed drive and the dump gate actuator to selectively create gaps before and after a stream of defective folded and glued cartons and dump the defective folded and glued cartons at the dump gate.

The invention relates to a device for feeding products in sheets into an insertion device before a digital printer, including a lifting system for a stack of laminar elements, which in turn includes an extraction mechanism for the last board, an insertion system with an advance mechanism, a rotation system for the stack(s), a positioning stop, connected to an advance and reverse mechanism, a squaring and scaling station, able to create a loading and accumulating hopper, and a telescopically-adjustable transportation system, with the capacity to move the previously-scaled sheets until the insertion device is fed.

The invention relates to an installation for printing and die-cutting laminar bodies, which comprises a digital printing station (1) for printing at least one face of the laminar bodies, and a die-cutting station (2) for die-cutting the laminar bodies coming from the digital printing station (1), comprising first conveying means (3) for moving the laminar bodies (P) positioned between the digital printing station (1) and a redirection station (5), and second conveying means (4) for moving the laminar bodies between the outlet of the redirection station (5) and the die-cutting station (2), The digital printing station defines an axial direction of travel and the die-cutting station (2) defines an axial direction of travel that is perpendicular to the axial direction of travel of the laminar bodies in the digital printing station (1), such that an L-shaped path of the laminar bodies (P), viewed in the plan view, is defined.

The present invention concerns a method for joining the ply of a reel of paper in depletion with the initial flap of a new reel, as well as an apparatus adapted for carrying out such a method. Thanks to the method according to the present invention, and to the apparatus suitable for carrying it out, the joining of the reels takes place without using gluing means, like for example the double-sided tape used in known methods, avoiding the relative drawbacks, the adhesion between the plies of the reels to be joined taking place by electrostatic attraction.

A conveyor belt includes: a support structure; a mobile belt; a plurality of rollers, which are associated to the support structure and are suitable to support and move the belt along a closed path. The plurality of rollers includes a drive roller and at least three idler rollers. Two rollers are supported directly by the support structure, while two rollers are supported by a mobile frame, which is slidingly associated to the support structure to be moved between a retracted position, in which a roller arranged at the second end is positioned completely inside the support structure, and an extracted position, in which the roller protrudes outside the support structure. In the transition between the two positions, the length of the useful conveyor area of the belt varies and is compensated by an equivalent variation in length of another portion of the closed path.

Disclosed is a conveying apparatus and method for conveying a tire layer, wherein the conveying apparatus includes a swivel conveyor with at least one endless belt or wire, a first pulley, a second pulley and a third pulley that define a minimal loop (L) for guiding the endless belt or wire along a conveying run and a return run, wherein the third pulley is arranged between the conveying run and the return run, and is swivable about a swivel axis (X) between a first swivel position and a second swivel position. The pivot position is chosen such that the length of the minimal loop when the third pulley is in the first swivel position is the same within a tolerance of less than 1 percent with respect to the length of the minimal loop when the third pulley is in the second swivel position.

A positioning and conveying device includes an endless conveyor belt which runs around two rollers mounted to a frame. The outer surface of the roller is defined by a plurality of roller segments which complementary cover the perimeter. The segments are individually movable in the axial direction for laterally moving the conveyor belt relative to the frame. The device includes at least one actuator assembly including a controllable magnetic actuator mounted at either end of the roller. At either end of the segments a ferromagnetic counterpart is mounted to cooperate with the respective magnetic actuators to move the respective segments in the axial direction. Each magnetic actuator comprises an electromagnet. Each ferromagnetic counterpart is arranged on a radial inner side of the associated segment. During rotation of the roller the roller segments and the associated counterparts follow a circular trajectory during a part of which they face the corresponding electromagnets.
