Description

254001

SUMMARY OF THE INVENTION The present invention provides a device for the production of fluffy or sheet materials for the application of liquid and / or sheet materials. pasty polymeric compositions, the compositions thereof are incorporated into support formations. The production of plastic masses by reinforced glass fibers or the production of insulated plastics is carried out in devices characterized in particular by two-folds, namely the second plastic applied to the support and the type of support structure. We coincide with the procedures where the devices work in combination of temperature-pressure (Jap. Patent 0101550). However, the load of the equipment operates on a temperature basis. For example, polyvinylchloride-based and glass fiber-based laminated plastics are produced in an apparatus wherein the laminating material is placed on a plastisol layer at a thickness of 0.1 to 0.5 mm and heated to 30 to 150 ° C for 30 minutes. to 120 a (Jap. U.S. Patent No. 4,129,075; NSR Pat. No. 2,827,574; U.S. Pat. No. 4,263,199). Another is a glass fiber coating machine, followed by heat treatment at temperatures of 120 to 200 ° C (Belg. Pat. 847 788, US Pat. No. 535 173).

According to the present invention, a device for encircling non-metallic profiled materials consists of a unwinding and winding device, a coating device, a heating device and a cooling part, wherein a preheating device 2 is located downstream of the profiling material recovery device by an internal opening of the same profile as the unwound profile material. followed by a coating device 3 consisting of a deposited material container and a dimensional and shaped member 3b, preferably with an axis in a vertical direction, followed by a final-heating portion 4 and a cooler 5, preferably with direct contact of the liquid heat exchange material with the drawn profile material and finally the winding device 6 is included. The advantage of the processing of the materials according to the invention is the very good adhesion of the applied, especially plastic, or thermoplastic materials to the support material, and in fact that the applied material is applied to the preheated carrier material, which passes through further heat treatment after the transition through the molding element, most often through a nozzle or slit. A further advantage of the device according to the invention is the substantial shortening of the thermal position of the coating material it does not exceed 0.1 to 1 s depending on the thickness of the deposited layer at 40 to 210 ° C.

Due to the short exposure time of the plastisol or the molten or dissolved polymer, the device according to the invention can be minimized and considerable energy savings can be achieved.

The device according to the invention can be processed continuously but also semi-continuously and broken.

The profiled material to be encapsulated is unwound from the unwinding device, usually also with the braking system, to ensure its proper tension. The effect of changing the diameter of the wound material can be eliminated by the replacement member. The film material is fed to a preheating device in which the heating is heated so that the temperature in the working area of the screen is necessary for the effective deposition of the blowing material. The inner opening of the pre-heater is similar in shape to the transverse sleeve of the profile material, but it is densely enlarged, as a rule, the distance of the surface of the profiled material from the inner walls is in the range of 0.1 to 1 mm. The most useful source of heating is the use of electrical energy, in particular with heat recovery. Less effective is induction and high frequency heating. Heating by supplying a preheated heat exchange medium may also be used.

A further member is followed by a coating device in which the deposited material reservoir is generally heated to a temperature ensuring the liquid state and the desired viscosity-deposited material. The mass applied to the preheated film material is shaped and dimensioned to ensure even distribution of the material. A further homogeneous distribution of the deposited material provides in the final heating portion a heating option analogous to that of the preheating device. The coating material is fixed to the coating material, the most thermoplastic materials, preferably by direct cooling with water or other liquid, depending on the solubility of the deposited material in the cooling medium. As a rule, water is used for macromolecular solutions for their practical insolubility.

After cooling, the extruded profile material in the winding device is wound up, spooled, and the material is evenly deposited throughout the winding area of the spool, thus also compensating for the change in winding cross section. Part of the device formed by the preheating device to the cooler can be arranged in the production line.
