Definitions
- the invention relates to a device for trouble-free product conveyance in folders, both by a gap between two product-carrying cylinders and by a gusset area extending behind it, which is delimited laterally by peripheral surfaces of both cylinders and at the top by a guide device for the product to be conveyed.
- DE 37 05 195 A1 shows a guiding device in the cylinder gusset of two interacting cylinders.
- a rotating part mounted with bearing stubs has adjustable connecting pieces which ensure continuous guidance of the leading product section, but leave the trailing product section moving out of the cylinder gap into the gusset area to itself.
- a transverse folding device similar to the guide device disclosed in DE 37 05 195 A1 is disclosed in DE 35 12 308 C2.
- This cross-folding device also has a rotatable middle part, the connecting pieces of which, however, are designed to be fixed with a tangential transition. The trailing end of a folded product passing through the gap between the folding cylinder surfaces cannot be guided with this transverse folding device either.
- DE 33 21 577 C2 discloses brake brushes in the folder of rotary printing presses.
- the circumference of a folding knife cylinder employed brake brushes can only be influenced on a trailing end of the product.
- the area of action of the brake brushes in the lower gusset area between the folding knife cylinder and the jaw cylinder is limited by the contour of the lower cylinder gusset.
- the holding and braking force exerted by the brushes no longer acts, so that the trailing end of the product entering the cylinder gap is suddenly relieved and tends to compress in the upper region of the cylinder gusset.
- the fluttering and whipping movements of the trailing product section in turn disturb the movement sequence of the leading product section and are therefore highly undesirable.
- the invention is therefore based on the object of optimizing the transition from folded product areas of a folded product between product-carrying cylinders.
- this object is achieved in that a coating is applied to a cylinder receiving a product and has a plurality of chambers which can be closed by sections of the moving product.
- the coating on the circumference of a cylinder taking over the product, viewed in the direction of product movement, is arranged in front of a gripping device.
- the coating extends on the circumference of the cylinder receiving the product on both sides of a cylinder center running between the cylinders.
- Fig. 1 the transition of a folded product between two product-carrying cylinders is shown.
- a product 6 guided on the circumference of a folding knife cylinder 1 is held on the circumference of the folding knife cylinder 1 by punctures 3, supported by adjustable brushes 4.
- the product spine is pushed into a folding jaw 8 of a folding jaw cylinder 7 by a folding knife 2 parallel to the product 6, depending on the operating mode, whether the second transverse fold or the delta fold is being driven.
- the fold flap 8 gripping the fold back of the product 6 pulls the product released by the punctures 3 off the circumference of the fold knife cylinder 1.
- the leading product end 6a is continuously guided along a guide plate 5, while the trailing product end 6b leaving the effective area 4 of the brushes 4 enters the gap between the product-guiding cylinders 1 and 7.
- a coating 10 is applied, the extent of which is dimensioned on the circumference of the jaw cylinder 7 in such a way that both the trailing end of the product 6b is simply cross-folded as well delta folded products 6 can be included.
- compression of the coating 10 forces air out of the individual chambers 11 lying one behind the other in the circumferential direction.
- the openings of the chambers 11 are closed by the trailing end 6b of the product, which clings to the surface of the coating 10. If the trailing end 6b of the product lying on the coating 10 moves out of the gap, the coating 10 (see also FIG. 3) returns to its original thickness.
- Fig. 2 shows a strip-shaped coating section.
- the coating 10 can be designed as a plate covering a complete section of the cylinder jacket of the jaw cylinder 7, or it can consist of individual strips arranged side by side in the axial direction.
- the plates can be traversed by ventilation channels, particularly in the middle area.
- the chambers 11 have a teardrop-shaped contour, the narrowest point of the contour being oriented in the direction of product movement 15. It would also be conceivable to have oval contours, longitudinal slots or similar contours of the individual chambers 11, as well as a sequence of different geometries both in the circumferential direction and in the axial direction of the jaw cylinder 7.
- the compressible coating 10 can be considered to be largely inelastic Executed pad 12 may be provided with which it can be attached to the circumference of the jaw cylinder 7.
- the thickness of the incompressible base 12 can be used to set the ratio of the compressible coating 10 to the incompressible base 12. Since the chambers 11 are in the compressible coating 10, the compression produces a briefly acting suction force. With different paper basis weights, 12 different production requirements can be taken into account by the choice of the base.
- Fig. 3 shows compression and decompression of the coating during the passage of the gap between the product-carrying cylinders.
- a coating 10 extending in the circumferential direction of the folding jaw cylinder 7 on both sides of a cylinder center 9, be it in strip form or as a plate structure, the forces which can be influenced in the gap by the compressibility of the coating can be used for product guidance in the upper gusset region 14 without it being more complex Internals there.
- the coating 10 each be attached to the cylinder jacket in such a way that this - in the direction of rotation of the cylinder taking over the folded product - is arranged in the rear region of the jacket segment of the cylinder covered by one product each. This ensures that the trailing product ends 6 b, even in the case of cylinders with multiple large folding products, pass safely through the cylinder gap into the upper cylinder gusset 14, where the holding force gradually decreases after atmospheric pressure compensation through the walls of the chambers 11.
- the gentle compressive force acting in the gap also provides a tensile force which permanently tightens the trailing end 6b of the product, which counteracts wave formation.
