Patent ID: 8585389

Claim:
Device for manufacturing a rubber strip material comprising cord material, wherein the device comprises: an extruder with a conveying screw for extruding unvulcanised rubber around the cord material for the purpose of producing a continuous rubber strip, wherein the extruder is provided with an integrated gear pump with adjustable pump speed, a control unit for adjusting the pump speed of the gear pump, wherein the device further comprises: a pull-out unit comprising a pull-out roller, driven by a motor, for pulling the rubber strip out of the extruder, wherein the motor is a controllable motor for driving the pull-out roller with controllable drive speed; a buffer unit provided with a number of lower and a number of upper reversing rollers, wherein the distance between the upper and lower reversing rollers is adjustable; and a distance measuring unit for measuring the distance between the upper and lower reversing rollers and for emitting a distance signal; wherein the pull-out unit is placed between the extruder and the buffer unit; and wherein the distance measuring unit can be connected to the controllable motor of the pull-out unit, wherein the drive speed of the pull-out roller can be controlled at least based on the distance signal.
