    A method and apparatus for the continuous manufacture of extruded material such as chip board, plastic board and similar materials, in which the material to be pressed is conducted, in a pressing section, between endless forming bands which co-circulate the feeding direction of the extrusion, extend over the width of the extrusion and through which pressure and optionally heat are introduced into the material. To aid the feed and reduce stresses, at a point following the pressing section, a pulling force in the feeding direction is exerted on the extrusion of the finished material.

    The invention relates to mechanical engineering, in particular to methods for the production of prolyl products and devices for their implementation.
    A known method for the continuous manufacture of extruded core materials, such as particle plastic plates, consists in compacting the material at the extrusion site between endless, if necessary, heated Lorma plates with a width equal to the width of the material to be compacted by synchronously moving them in the direction of promotion of the compressible material and A device for the ocyi of this method comprising a belt press comprising two endless molding belts with widths at the pressing section oh, equal to the width of the material being compacted, mounted with the possibility of synchronous
    rewinding in the direction of advancement of the compression material, as well as supporting units located on both sides of the material being compacted.
    In the known device, the pressing of the material was os1 (the product is between two endless ribbons 1.
    The disadvantage of this method and apparatus is the impossibility of obtaining
    plates of great thickness.
    Lel of the invention is to provide the possibility of obtaining plates of great thickness.
    This goal is achieved in that according to the method of continuous manufacture of extruded profile materials, such as plastic particle boards, and similar materials, consisting in compaction of the material in the extrusion section between endless, if necessary, heated molding bands with a width equal to that not compacted. material, by synchronously moving them in the direction of promotion of the pressed material, in the zone located behind the pressing section, on the compacted material comfort the traction force in the direction of advance of the material to be pressed. In this case, the traction force affects the material continuously. The material to be compacted is moved at the compression section periodically with a predetermined rhythm, and the material is periodically affected by the tractive force during the phase of its translational movement. This goal is achieved by the fact that a device for carrying out the method, comprising a belt press comprising, at the press section, two endless molding belts with a width equal to the width of compacted material, mounted with simultaneous movement in the direction of advancement of the pressed material, as well as support units arranged along both sides of the material being compacted, equipped with a pulling mechanism placed behind the belt press mounted with the possibility of interaction with the external surface rel release material When this traction mechanism is configured as an additional belt press with endless belts placed on either side of the direct extruding material. The traction mechanism is made in the form of at least one pair of drive drums with axes perpendicular to the direction of movement of the material being compacted on both sides of the pressed material and mounted on their surfaces on axes parallel to the axes of the drums. , with the ability to rotate the slats facing the opposite surfaces of the compressed material. The traction mechanism is also made in the form of at least one pair of drive rolls located opposite each other on both sides of the compacted material, axes that are perpendicular to the direction of movement of the compacted material and turned to opposite surfaces of the compressed material. The traction mechanism is designed as a device for clamping the compacted material from both sides and driving the reciprocating movement of this device in the direction of movement of the material being compacted, the drive being mounted on a belt press and associated with the device for clamping. The clamping device is made in the form of a lever system for converting a pulling force of said drive to a clamping force. Figure 1 shows a device for implementing a method for the continuous manufacture of extruded profile materials; on L) ig.2-4 - constructive versions of the tension mechanism. The device contains a belt press comprising two endless molding belts 1 and 2, which interact in the area of pressing 3 with the pressed material 1 4. The belts 1 and 2 are mounted with the possibility of synchronous movement on the drums 5-8. Inside the molding belts 1 and 2, supporting units are installed, including, interconnected by brackets (not shown), racks 9 and 10. Plates 11 and 12 are placed between the supporting racks 9 and 10, in which channels and heating elements are installed. Roller chains 13 and 14 are located between facing plates 11 and 12, along which the molding belts 1 and 2 roll. Rollers of roller chains 13 and 14 are installed in such a way that pressure and heat are transferred to the molding belts 1 and 2 through them. At the exit of the belt press, a pulling mechanism is installed. The gripping mechanism see figure 1 can be made in the form of a similar belt press comprising two endless belts 15 and 16 mounted with the possibility of synchronous rotation on the drums 17-20. The current mechanism shown in FIG. 2 is made in the form of at least one pair located opposite each other on both sides of the compressible material 4 of the driving drums 21 and 22 mounted on axes 23 and 24. In the drums 21 and 22 on the axis x 25 parallel axes 23 and 24 are installed with the possibility of rotation of the strap 26, facing the opposite surfaces of the compressible material 4. The thrusting mechanism shown in (Kg. 3 can be made in the form of drive rolls 27 and 28. For to increase the adhesion on the rolls 27 and 28, the burner 29 is made in the form of ribs, spikes etc. The T drive mechanism shown in FIG. 4 can be made in the form of clamps, including pads 30 mounted in housing 31 on the arms 32, and a reciprocating drive made in the wig de cylinders 33. rods 34 which pivotally connected to the levers 32.
    The device works as follows.
    The raw material enters the working space between the belts 1 and 2 and as it passes between them it heats up and compresses.
