The tire pad is used to prevent the rim from damaging the inner tube. Therefore, in order to better protect the inner tube, the correct pad size must be selected according to the rim width. The rim must be kept clean and the shape is smooth and the surface is smooth. Therefore, Cushion Press on Tires it is important to check the rims at the same time when inspecting the damaged straps.

The pad is usually a textile product and has many different embodiments. Cushion Press on Tires A pressure pad as described in DE-B-2319593 comprises a woven fabric in which the woven fabric is completely embedded in a cushion made of a silicone elastomer constituting a substrate. For example, additives made from powdered copper and / or aluminum and / or aluminum bronze powder and / or graphite and / or ferrosilicon may be incorporated into the silicone elastomer in order to improve the thermal conductivity of the underlayer.
This type of pressure pad proved to be successful because the cushion made of silicone elastomer was able to withstand the temperature in the laminator, which could exceed 200 ° C and also because it had good long-life bounce characteristics, Resulting in a permanent print (because of the shape of the pressed plate, also known as "open window"). It is also advantageous that the thread of the holder is physically secured by the cushion, so that the pressure pad has good dimensional stability.
In order to increase the productivity, it is desired to make the working cycle of the laminator become shorter and shorter. This requires the rapid transfer of heat from the hot plate to the pressing material, i.e. the pad must have a high thermal conductivity in the thickness direction.
Despite the presence of metal fabrics and additives that promote thermal conductivity, the known pressure pads do not satisfactorily meet these requirements. It is an object of the present invention to form a press pad of the type initially described so that the pressure pad is also suitable for a laminator having a shorter duty cycle, in particular to ensure that heat is quickly transferred from the heating plate to the pressing material.
According to the present invention, Cushion Press on Tires this object is achieved by a presser in which the thickness of the underlayer is less than the thickness of the holder and the backing layer is such that the heat-conducting wire protrudes beyond the cushion layer on both sides of the pad Embedded in the stent. Thus, the basic idea of the present invention is to cause the thermowell to protrude at least partially on the outer side of the pressure pad beyond the cushion and to protrude on the flat side of the pad so that, on the one hand, ), Cushion Press on Tires And on the other hand forms a direct contact with the Pressing Sheet. It has been found that this can greatly promote heat transfer in the thickness direction. Through the number and thickness of the heating wire, especially the contact area, the thermal conductivity along the thickness direction can be optimized according to the special needs. Cushion Press on Tires It has also been surprisingly found that, despite the reduced thickness of the cushion, the cushioning performance has not deteriorated, and in fact has improved. And there is no ability to weaken the pressure pad in the form of isobaric and the ability to deliver the pressure of the press to the entire surface. Did not find "open window" situation.
Since the cushion layer is generally thinner than the cushion layer of the pressure pad described in DE-B-2319593, the pressure pad of the present invention can also save material and it is also lighter. Therefore, the manufacture and transportation of the pressure pad is more economical. But also to simplify its handling.
