  • Publication number: 20150210471
    Abstract: The invention relates a device for suctioning off waste products of the production machine comprising a suction chamber at which at least a suction element is assembled which extends into a suction space, which is outside the suction chamber in order to convey waste products into the suction chamber, wherein the suction element comprises an inlet area, which is facing the suction space and an outlet area, which ends in the suction chamber. According to the invention, the suction element comprises a circumferential wall, which is configured with such a curved distribution that during the suctioning a middle negative pressure zone results in the outlet area spaced apart from the wall, which comprises a lower negative pressure than the negative pressure, which results in the outer negative pressure zone between the middle negative pressure zone and the wall wherein the waste products within the suction element flow through mainly in the middle and a contacting of the waste products at the wall can be minimized.

  • Patent number: 6702563
    Abstract: An extruder die head for producing multilayered tubes made of thermoplastic material exhibits a central annular channel, which is provided with an annular outlet die. Into the outer limiting wall of the channel empty annular slits, which feed a polymer melt and which constitute the smaller diameter openings of truncated channels, formed between the internal and external shells of stacked, conical insert members. To reduce the axial length of the extruder die head, the annular slits, feeding the polymer melts, also empty into the inside wall of the central annular channel. The annular slits are the smaller diameter openings of truncated channels, formed between the internal and external shells of stacked conical internal insert members.

  • Patent number: 6565347
    Abstract: An extruder die head comprises an internal cylindrical mandrel and a shell, which encloses said mandrel concentrically. Between said mandrel and shell an annular channel is formed that empties into the die slit. A polymer melt is fed through a line to the annular channel. To prevent the polymer melt in the area of the start of the annular channel from penetrating into a slit that forms between the mandrel and the shell due to heat expansion, there is between both mandrel and shell a ring with such a coefficient of thermal expansion that when heated up due to the polymer melt said ring seals the slit between the shell and the mandrel.
