Definitions
- the invention relates to a transport drum in rotary printing machines with an elevator to prevent smearing of a fresh printed product when transporting it through the machine, the elevator on the Shell surface of the transport drum is attached and made of a carrier material there is attached thread-like support elements.
- the object is achieved in that the support elements are resilient and that at the outer ends of the support elements paint-repellent material is applied. Due to the resilient training of Support elements can be a relative movement of the printed product on the Follow the transport drum without any movement between them and the Print product itself takes place. After the printed product the transport drum has left, the individual support elements spring back to their starting position back. By applying a color-repellent material to the outer The end of the support elements prevents the transfer of color particles and thus damage to the printed image. It also makes the Support area for the printed product enlarged, so that penetration of the Support elements in the printing ink is also prevented. Still will created very small support points for the printed product, so that a damage-free transport of the same is guaranteed.
- the Support elements applied a small amount of chrome.
- Chrome is a color-repellent material, which has the additional advantage that the Support elements have a high wear resistance.
- the support elements attached obliquely in the carrier material, so that depending on the material of the support elements a high suspension of the same is achieved.
- a further advantageous embodiment of the invention is characterized in that that the support elements are designed to be resilient radially to the transport drum.
- the resilient training can e.g. B. in loop form or in spiral form Supporting elements can be executed.
- a resilient Training of the carrier material improves the spring action of the support elements be, so that a relatively stiff material for the support elements use Can be found. This also allows the support elements not only in circumferential and Longitudinal direction of the transport drum, but also in the radial direction, so that improves the handling of the transport drums and lubrication of the Print products are prevented with certainty.
- the support elements 7, 8, 9 are resilient and are radial to FIG Carrier material arranged. You can do this as indicated by arrows in all Directions spring and move after transporting the printed product back to their starting position.
- At their outer end are at the Support elements 7, 8, 9 applied ink-repellent caps 10, which preferably are made of chrome and galvanically attached. This color-repellent Material is applied in small quantities and takes about one when applied Spherical shape.
- support elements 8 are shown which are resilient radially to the transport drum 2, 4 are trained.
- the support elements 8 can be a loop shape or a Have a spiral shape to achieve a high spring effect.
- the support elements 9 4 are arranged obliquely in the carrier material 6, so that this also a high spring effect is achieved radially to the transport drum 2, 4. At the same time they can move relative to the carrier material 6, so that damage of the printed image is excluded.
