Abstract: A folding table, in particular for a folding device which is provided with a chopper folding device, includes a folding face which is suitable for receiving a flat product to be folded, and a folding aperture which extends in a conveying direction, the table extending along a table plane. The folding face includes guides which are capable of guiding at least one conveyor for conveying a flat product to be folded in the conveying direction.

Abstract: A method adapted for a chopper folder, including a pair of parallel folding rollers defining between them an interstice, a mobile folding blade to force a flat product in the interstice, a means for adjusting the gap between the two folding rollers and a device for controlling the adjustment device. According to the method of the invention, at the beginning of a new production, the controller implements a production beginning mode, wherein it controls the means for adjusting the gap for the adjustment of the gap at a determined reference value, then a production mode, wherein it controls the means for adjusting for a gap adapted to the new production at a steady state.

Abstract: This table for a chopper folding device comprises a surface (20) for application of products to be folded (17), the application surface (20) extending along an application plane (PA), a folding opening (22) suitable for the passage of the products to be folded (17), at least one first guide portion (28) disposed adjacent to the folding opening (22) and comprising a first guide surface (32) inclined with respect to application plane. The table (12) comprises guiding means suitable for urging the product to be folded towards the first guide surface (32) and a first main suction hole (36) which opens on the first guide surface (32).

Abstract: This device for braking a flat product, in particular a signature, has a support, a brake shoe for braking the flat product, the brake shoe being movable between a position allowing the passage of the flat product and a position effecting braking of the flat product, and a drive for driving the brake shoe from the passing position towards the braking position. The drive includes an eccentric element which is movable in rotation and co-operates with the brake shoe.

Abstract: A folding roller is provided for a device for folding a flat product to be folded which extends along a center axis and includes a first axial portion and a second axial portion, the first axial portion having a first surface for folding the product to be folded. The second axial portion includes a main relief which is radially recessed relative to the first folding surface.

Abstract: A fan delivery for a folding apparatus is provided, having at least one fan wheel including a number of fan-wheel elements and having a signature guide member that is movable relative to the fan wheel, in which the signature guide member has at least one arm that is introducible into a space defined by two fan-wheel elements. A folding apparatus is also provided.
