Embodiment Construction

[0017] exist figure 1 A side view of an apparatus 1 for producing strips is schematically shown in . The device 1 comprises an unwinding device 2 provided with a reel 3 on which there is cord material. Typically the cord material is steel cord, although synthetic cord material can also be used.

[0018] The device 1 also comprises: an extruder 4 for extruding unvulcanized rubber around the cord material; and a buffer unit 5, here provided with a buffer circuit for buffering and cooling the extruded rubber. extruded material. Discontinuities in processing are also allowed here. Since here the continuous rubber strip is provided with longitudinal wires, the rubber strip has little tendency to stretch or otherwise deform. The buffer unit 5 is provided with a plurality of upper reversing rollers 6 and lower reversing rollers 7, wherein the distance between the upper reversing rollers and the lower reversing rollers is adjustable.

[0019] The continuous strip of rubber thus o...

Abstract

Device for manufacturing a rubber strip material comprising cord material. The device comprises an extruder with an integrated gear pump with adjustable pump speed and with a conveying screw for extruding unvulcanised rubber around the cord material for the purpose of producing a continuous rubber strip. The device furthermore comprises a control unit for adjusting the pump speed of the gear pump, a measuring unit for measuring the height and the width of the rubber strip and for emitting a measuring signal indicative of the measured height and width. The measuring unit can be connected to the control unit for adjusting the pump speed of the gear pump for emitting the measuring signal to it, wherein the pump speed of the gear pump can be controlled by the control unit at least based on the measuring signal.

Description

technical field [0001] The invention relates to a device for manufacturing rubber strip material including cord material according to the preamble of claim 1 . Such rubber strip material comprising cord material may be the case of so-called belts, or may be the case of so-called "strands" formed by textile fibers at an angle of 80° to 90°, said belts being for example made with cords Reinforced rubber strip material in which the cords are formed from steel cords or synthetic fibers eg at an angle of 15° to 70°. Background technique [0002] Such a device is known, for example, from Japanese patent application 200595656. In this document, an extruder with a gear pump whose pump speed is adjustable is described. This adjustability serves to keep the delivery of the volume of product constant. When eg tape layers of other sizes have to be produced by the known device, changing the settings of the extruder takes a lot of time, during which time the device is not productive. ...
