<p>PURPOSE:To obtain the titled attachment wherein a rubber hardly stagnates, by a method wherein a stagnant flow of a rubber at an outside wall part of a passage at a confluent point is deflected by a specified quide part. CONSTITUTION:Circumferential rubber flows divided to the left and the right in an annular passage 2 are mixed into complicated rubber flows in the attachment A, and the mixed flow is deflected to be an axial flow along a supplying hole 3. In this case, the rubber tends to stagnate at the outside wall part of the passage 2 at the confluent point. This stagnation is prevented by providing the guide member 6 which smoothly deflects outer-layer flows of the rubber. Accordingly, the problem of defects in an article due to burning of the stagnating rubber or the like is solved, and labor such as overhauling is unnecessitated.</p> |
