Embodiment Construction

[0043] The following is based on Figure 1 to Figure 7 The device 1 according to the invention for supplying a screw extruder with a material strip 2 of a rubber compound or a plastic compound is explained in more detail. First, the material strip 2 is prepared in a zigzag or rocker-folded arrangement and is fed by means of at least one conveyor belt 3 to the feed area 4 of the at least partially funnel-shaped feed element 5 and then to the extruder 6 or by means of at least one conveyor belt 3. A conveyor belt 3 feeds the extruder 6 via a feed region 4 of an at least partially funnel-shaped feed element 5 .

[0044] Such as figure 1 As shown, in the feeding area 4, between the inlet and the feed rollers of the extruder 6, a motor-driven conveying device 7 for the material strip 2 is arranged, the conveying device has a surface capable of feeding the material strip 2 Adjacent, reversible pressure surface 8. The pressure surface bears against the surface of the material stri...

Abstract

An apparatus (1) for feeding a screw-type extruder (6) with material strips (2) made of rubber mixtures or plastics mixtures, which strips (2) are arranged in a folded zig-zag shape and can be supplied by means of at least one conveyor belt (3) to a supply region (4) of a supply element (5) that is funnel-shaped, at least in portions, and an extruder (6). A motor-driven conveyor device (7) for thematerial strip (2) is arranged within the supply region (4), which device comprises a pressure surface (8) that can abut the surface of the material strip (2) and can be moved in a reversing manner.Said pressure surface (8) only abuts the surface of the material strip (2) in the conveying direction (9) and, in the direction opposite the conveying direction (9), it adopts a return position in which it is spaced from the surface of the material strip (2).

Description

technical field [0001] The invention relates to a device for supplying an extruder, in particular designed as a screw extruder, with a material strip made of a rubber compound and / or a plastic compound, the material strip being in particular zigzag or The rocking arrangement is provided and can be fed to the extruder by means of at least one conveying device to at least a section of the funnel-shaped feed area of ​​the feed element or via at least one section of the feed element by means of at least one conveying device A section-funnel-shaped feed area feeds the extruder, wherein a motor-driven conveying device for the material strand is arranged within the feed area. Background technique [0002] When feeding rubber compounds and / or thermoplastics to screw extruders, practical operation of such plants depends on a high continuity of material composition and feed in order to obtain an optimum end product. [0003] In most cases, the mixture to be processed is provided in t...
