Definitions

the invention relates to a device for a slit-shaped holding device for fastening plates, preferably rubber blankets, with bent ends in a narrow, axially extending slot of a cylinder of a rotary printing press.
US-PS 25 25 003 a device for fastening a rubber blanket unit consisting of a rubber blanket and a carrier plate is described.
the rubber blanket unit is provided with two folded ends, on each of which a folded leg of the carrier plate projects beyond the ends of the rubber blanket and the rubber blanket on the carrier plate ends in the region of a bevel delimiting the legs.
These chamfered legs are inserted into a narrow, approx. 3.5 mm wide slot.
a wedge is arranged between opposite side faces of the two legs, whereby one leg is pressed against one side face of the slot.
the blanket unit is thus held frictionally in the slot by means of a holding device designed as a wedge.
DE 35 38 308 C2 shows a device for winding of a blanket on a blanket cylinder of a web-fed rotary printing press.
the blanket is connected to a dimensionally stable support plate to form a blanket unit.
a bent leg of the carrier plate projects beyond the rubber blanket, while at a leading end, a bent leg is coated with the rubber blanket.
DE-PS 19 60 635 an arrangement for fastening flexible printing plates on a plate cylinder is shown.
the holding device described here consists of at least one axially extending slot made in a lateral surface of the plate cylinder. Folded plate ends are received from this slot.
the invention has for its object a device for a device for attaching a plate, preferably a blanket unit, in to create a narrow, axially extending slot of a cylinder of a rotary printing press, which largely prevents dirt and ink from getting into the narrow slot.
the advantages which can be achieved with the invention consist in particular in that a gap remaining between two ends of a rubber blanket is largely closed and nevertheless a fastening of rubber blanket plates is possible.
the filler of the device according to the invention protects the free ends of the rubber blanket on the carrier plate against unnecessary wear.
the already small vibrations, which are reduced by the narrow slot, are reduced even further as a result of the channel runout.
the advantages of the plate-shaped rubber blankets can be used without having to accept the disadvantages of the rubber blanket sleeves.
the device according to the invention is shown in the drawing and is described in more detail below.
a cylinder e.g. B. a blanket cylinder 1, a rotary printing machine for receiving, for example, formed as blanket units 2 plates with folded ends 3, 4 with at least one parallel to its axis of rotation, extending from a lateral surface 6 of the blanket cylinder 1 into its interior 7, narrow slot 8 Mistake.
the rubber blanket 11 is fastened to the carrier plate 9 in such a way that both legs 12, 13 of the carrier plate 9 are free of the rubber blanket 11 at the bent ends 3, 4 of the rubber blanket unit 2 and thus only the two legs 12, 13 of the carrier plate 9 into the slot 8 protruding.
the slot 8 is preferably rectangular in cross section.
a bore 18 running parallel to the slot 8 is made in the rubber cylinder 1.
the slot 8 tangent to the bore 18 in the form of a chord, so that the bore 18 is connected to the slot 8.
there is a virtual continuation of a lateral surface 19 of the bore 18 at a distance a from a side surface 21 of the slot 8 facing away from the bore 18, the distance a being slightly greater than the thickness d9 of the carrier plate 9, for. B. a 0.4 mm.
This spindle 22 is provided in the axial direction with a plurality of pressure pieces 23 acting radially outwards.
the pressure pieces 23 are fastened in the spindle 22 in such a way that their pressure cams 24 can act resiliently beyond a lateral surface 26 of the spindle 22.
the pressure cams 24 are provided at their outer end with a ball dome, but cylinder segment-shaped configurations are also possible, so that, for example, one for each pressure cam 24 line-shaped contact zone results.
Beta 70 °
a flexible but pressure-resistant leaf-shaped slide 32 is suspended, which in the present example is designed as a continuous steel leaf spring.
the other, outward-facing end 30 of the slider 32 is connected to a filler 33 in a form-fitting and / or material-locking manner.
the slider 32 can also be designed like a comb, the filler 33 can be attached to the comb back.
This filler 33 consists, for example, of an elastic material similar to the rubber blanket 11 which is vulcanized directly onto the end 30 of the slide 32 and extends axially along the length of the slot 8 or preferably over the entire width of the rubber blanket unit 2.
This filler 33 but can also consist of the same material as the slide 32 and be molded directly onto it. But it is also possible to form the slide 32 resilient, in which, for example, the end 30 is made of elastic material.
the slider 32 is provided with at least one barb 36 on its side surface 34 facing the trailing end 4.
a plurality of barbs 36 can also be arranged, which engage in corresponding recesses 37 in the leg 13 of the trailing end 4 which are adapted to the barbs 36.
the operation of the device according to the invention is as follows: In an insertion position (FIG. 1) of the spindle 22, the slide 32 located in the slot 8 with the filler piece 33 projects beyond the lateral surface 6 of the rubber cylinder 1.
the folded ends 3, 4 of the rubber blanket unit 2 are adapted to the angle of inclination alpha of the slot 8.
the spindle 22 is rotated counterclockwise until the pressure pieces 23 are approximately perpendicular to the legs 12, 13 of the carrier plate 9.
the pressure cams 24 of the pressure pieces 23 are pressed against the legs 12, 13 of the carrier plate 9 by means of spring force which is supported on the spindle 22.
the slide 32 with the filler 33 attached to it and the leg 13 attached to the barb 36 of the trailing end 4 in the Slit 8 retracted until the filler 33 fills the remaining gap 47 of the opposite ends 44, 46 of the rubber blanket 11.
the legs 12, 13 of the carrier plate 9 and the slide 32 are clamped in the slot 8 of the rubber cylinder 1 between the side surface 21 of the slot 8 and the pressure cam 24 (FIG. 2), with which the ends 3, 4 of the rubber blanket unit 2 are secured are attached to the rubber cylinder 1.
the spring force and spring travel are dimensioned such that a secure clamping takes place.
