| 摘要 |
The present invention relates to an arrangement for producing an elongated bar-like structure, comprising a material compression unit which functions to compress a mixture of plastic material and filler material and to press the compressed mixture through a nozzle (4) into a matrix (10) which includes matrix walls (11, 12, 13, 14) which are able to move in the feeding direction of the elongated bar-structure (A), wherein the movement pattern of individual matrix walls is adapted to enable the bar-like structure (A) to be fed through the matrix in a direction away from the material compression unit. Each of the matrix walls (11, 12, 13, 14) is in mechanical co-action with a disc (11a, 12a, 13a, 14a) which when rotated causes the associated matrix wall to move forwards or backwards. |
