EXTRUDER TOOLING Russian patent published in 2019 - IPC B29C47/02 B29D30/38 

FIELD: plastic processing.

SUBSTANCE: invention relates to an extruder tooling for placement in an extruder head and for forming an elastomeric strip with reinforcement cords. Technical result is achieved by an extruder tooling comprises a die for applying elastomeric material to the reinforcement cords and a cord guide for guiding the reinforcement cords in a guide plane towards the die. Cord guide comprises a lower cord guide member and an upper cord guide member which are arranged to be mated with each other on opposite sides of the guide plane with the reinforcement cords extending in between them. Extruder head is provided with a lower flow channel and an upper flow channel which are arranged to debouch, via a lower slit in the lower cord guide member and an upper slit in the upper cord guide member, into the die from opposite sides of the guide plane. Lower cord guide member and upper cord guide member are each provided with an inner body extending on the inside of the lower slit and the upper slit, respectively, with respect to the guide plane and an outer body extending on the outside of the lower slit and the upper slit, respectively. Outer bodies overlap the inner bodies in a direction normal to the guide plane. Bodies of the lower member are integrally connected and form a first integral member, and bodies of the upper member form a second integral member.

EFFECT: technical result is to reduce deviations of the dimensions of the parts of the extruder tooling and simplify its design.
