Definitions
- the invention relates to a blanket and a device for attaching a blanket to a blanket cylinder of a rotary printing press according to the preamble of claims 1, 4 and 5.
- a blanket tensioning device in which the blanket ends are each provided with a hanging rail. A first or leading end is placed in a lateral recess in the cylinder channel and a second or trailing end is pulled radially into the channel by means of a clamping bar and thus tensioned.
- the invention has for its object to provide a blanket and a device for attaching a blanket.
- FIG. 1 shows a partial cross section through a cylinder with the device according to the invention along the section line I - I of FIG. 2.
- FIG. 2 shows a top view of the end of a cylinder with the device corresponding to the representation according to FIG. 1.
- a blanket 03 z. B. On the outer surface 01 of a blanket cylinder 02 is a blanket 03 z. B. with a thickness a of about 2 mm and a width b of about 1000 mm.
- At the first and second end 04; 06 of the rubber blanket 03 is one - z. B.
- U-shaped - first reinforcement rail 07 and a second reinforcement rail 08 positively and / or integrally attached. They are sufficiently rigid with respect to their longitudinal axis. Cross-section, shape and section modulus are selected accordingly.
- the reinforcement rails 07; 08 each have their first (left) ends 12 and their second (right) ends 13 on the left and right beyond the rubber blanket 03 by at least five millimeters.
- the reinforcement rails 07; 08 are longer than the rubber blanket 03 is wide.
- the ends are 04; 06 of the rubber blanket 03 on the reinforcement rails 07; 08 z. B. attached by rivets or by gluing, vulcanization, etc.
- the reinforcement rails 07; 08 can each have a height f that is 20 to 40 times the thickness a of the rubber blanket 03.
- the ends 04; 06 of the rubber blanket 03 with the part of the reinforcing rails 07; 08 are inserted into the narrow cylinder channel 14, which runs approximately in the radial, axial direction of the blanket cylinder 02.
- the opening 16 to the lateral surface 01 is gap-like (internal width g).
- the cylinder channel 14 is expanded trapezoidally to a clear width h.
- a trapezoidal shape of the cylinder channel 14 is advantageous because thereby the reinforcing rails 07; 08 can be guided away from each other inside the cylinder channel 14.
- the width g of the opening 16 can be kept very narrow. It corresponds approximately to a thickness a of the rubber blanket 03 plus the thickness c of a reinforcing rail 07 plus a small addition.
- the cylinder channel 14 can be divided into two compartments 19 by a wedge-shaped guide web 18, which is fastened to the channel base 17 and projects in a wedge-shaped manner. 21 be divided lengthways. This makes it possible that each end 04; 06 of the rubber blanket 03 in its own compartment 19; 21 can be performed. Here, the reinforcement rails 07; 08 moved away from each other.
- a device 20 is provided for generating a compressive force on the free ends.
- the device 20 is supported on the blanket cylinder body and generates a compressive force on the free ends, which acts in the radial direction in the direction of the axis of rotation of the blanket cylinder 02 and thus holds and tensiones the blanket 03.
- the devices 20 for generating a compressive force are per free reinforcement rail end 07; 08 provided. They exist e.g. B. from a clamping block 24; 26, each by means of a releasable, positive connection - z. B. one screw 27; 28 - laterally next to the cylinder channel 14 of the blanket cylinder 02 in the direction of the cylinder rotation axis or radially up and down and so compressive forces on the free ends 12, 13 of the reinforcing rails 07; 08 can exercise.
- Each clamping block 24; 26 is secured against rotation and has z. B. in each case one of the free ends 12, 13 of the reinforcing rails 07 and 08 engaging around the nose 29.
- the clamping blocks 24; 26 are also at different distances from the outer surface 01 of the blanket cylinder 02 in the radial direction (FIG. 1). Thus, both clamping blocks 24 of the first (leading) end 04 of the rubber blanket 03 are further away from the lateral surface 01 than the clamping blocks 26 of the second (trailing) end 06 of the rubber blanket 03.
- the devices 20 are each secured in a recess 23 on the bale of the blanket cylinder 02. A wall of this recess 23 can serve as an anti-rotation device.
- the devices 20 can also be attached to both end faces 22 of the rubber cylinder bales.
- Thickness (03) b Width (03) c Thickness (07; 08) d Length (07) e Length (08) f Height (07; 08) g Width, clear (16) h Width, clear (16)
