A die for a polymer mixing machine includes first and second opposing surfaces. Each defines first cylindrical portions and second V-shaped portions interspaced between each first portion. The first and second opposing surfaces produce a ply with first portions thicker than second portions and throated portions therebetween.

The disclosure is directed to a method for manufacturing a Bowden cable, in particular a Bowden cable of a closure element arrangement of a motorized vehicle, comprising the step of applying a noise dampening sleeve to a Bowden cable housing. It is suggested that the noise dampening sleeve is molded onto the Bowden cable housing.

The invention relates to a process for producing a polypropylene composition using a first extruder comprising successive zones comprising a first zone, a second zone, a third zone and a fourth zone and a second extruder comprising successive zones comprising a first zone and a second zone, the process comprising the steps of: 1a) introducing a first propylene-based polymer in the first zone of the first extruder, 1b) melt mixing the first propylene-based polymer in the second zone of the first extruder, 1c) adding an additive masterbatch to the mixture of step 1b) in the third zone of the first extruder and 1d) melt-mixing the mixture of step 1c) in the fourth zone of the first extruder to obtain the polypropylene composition, wherein the maximum temperature in the fourth zone of the first extruder is lower than the maximum temperature in the second zone of the first extruder and is lower than 240° C., wherein the additive masterbatch is produced in the second extruder by a process comprising the steps of: 2a) introducing a second propylene-based polymer and organic additives in the first zone of the second extruder and 2b) melt mixing the mixture of step 2a) in the second zone of the second extruder to obtain the additive masterbatch, wherein the maximum temperature in the second zone of the second extruder is lower than the maximum temperature in the second zone of the first extruder and is lower than 240° C.

The present invention relates to the technical field of wire-rod production equipment, in particular relates to an automatic production line for conductive tape and a manufacturing method for conductive tape, Automatic production of conductive tape brings about high production efficiency and low cost; it not only conducts pretreatment and corresponding detections of the conductors in the production process but also conducts follow-up treatment and corresponding detections of the conductive tape and thus improves the production quality of the conductive tape; in addition, it marks the abnormality position of the conductive tape which is abnormal during the withstand voltage detection so that the operator can accurately find out the abnormal section of the conductive tape.

A method and a device for manufacturing a rubber coated cord, comprising: a rubber coated cord including a preceding cord is manufactured by causing the preceding cord to pass through a preceding head while filling the preceding head with unvulcanized rubber extruded from a rubber extruder, and a rubber coated cord including a next cord is manufactured by setting a leading edge portion of the next cord in a state where the leading edge portion of the next cord has passed through the next head in advance, manufacturing a predetermined length of the rubber coated cord including the preceding cord, and subsequently causing the next cord including a leading edge portion side range bonded to a trailing edge portion of the rubber coated cord including the preceding cord to pass through the next head while switching from the preceding head to the next head.

A die has an inner die that has a straight portion of circular columnar outer shape and a convergent tapered portion provided closer to an extrusion port side than the straight portion and an outer die that houses the inner die. A first supply passage connecting a first valve and a flow passage, a second supply passage connecting a second valve and the flow passage, and a third supply passage connecting a third valve and the flow passage are provided inside the die. Downstream side end portions of the first supply passage and the second supply passage are connected to a portion of the flow passage formed between the straight portion and the outer die and a downstream side end portion of the third supply passage is connected to a portion of the flow passage formed between the tapered portion and the outer die.

A method and system are disclosed. A method of printing onto a base having an upper surface spaced from a lower surface by a base thickness includes dispensing a yarn from a nozzle of a printing system and selectively attaching the yarn to a first attachment region. The step of dispensing the yarn includes dispensing a heat-moldable material and a melt-resistant material. The step of selectively attaching the yarn to the first attachment region includes moving the nozzle into the first attachment region. The step of moving the nozzle into the first attachment region reduces the base thickness by a prodding distance. The heat-moldable material bonds to the first attachment region.

A hose extrusion mandrel for manufacturing rubber hoses includes: a solid thermoplastic, elongate core; and a rubber compound outer layer covering a surface of the elongate core. A ratio between a diameter of the core and a thickness of the rubber compound layer may be between 8 and 11.

In a method of manufacturing a rubber coated twisted wire cord, when an outer circumferential surface of a twisted wire cord that is moving from an unreeling unit to a winding unit is coated with unvulcanized rubber extruded by a rubber extruder, by a coating unit disposed between the unreeling unit and a winding unit, in a state of additional tension being imparted on the moving twisted wire cord by a tension imparting unit disposed at a nearby position on an upstream side from the coating unit in a moving direction of the twisted wire cord, the unvulcanized rubber coats the outer circumferential surface of the twisted wire cord in this state to continuously manufacture a rubber coated twisted wire cord.
