移送することが出来る。 As described in detail above, the extrusion molding machine of the present invention has at least a surface pore size at the die tip of the molding machine body.
A support plate made of a continuous porous material with a diameter of 15μ or less is installed in series, and an air supply means is connected to the support plate, so that air can be freely blown out from the surface of the support plate.
The molded product can be floated above the surface of the support plate by the ejected air and then extruded and transferred. Therefore, compared to the conventional method in which the extruded product is moved in contact with a conveyor such as a belt conveyor, the present invention can transport the extruded product in a non-contact manner, thereby greatly reducing resistance and preventing deformation of the molded product. Damage can be prevented. In other words, in the past, extruded products were placed on a separately driven conveyor and transported, so if the extrusion speed and conveyor transfer speed did not match, the molded products could be stretched and stretched or compressed. Although deformation occurs, the present invention can extrude and transfer the molded product without deforming it, regardless of the extrusion speed of the molding machine main body.
又、支承板に供給する空気として熱風（又は温
風）を送り込めば、浮上移送と同時に成形物の下
面側又は全周面を効率良く乾燥できる利点を有す
る。 Furthermore, if hot air (or warm air) is sent as the air supplied to the support plate, there is an advantage that the lower surface side or the entire circumferential surface of the molded product can be efficiently dried at the same time as the floating transfer.
依つて、押出し後における後処理（次の工程）
を安心して行なうことが出来る押出成形機を提供
できる。 Therefore, post-processing after extrusion (next step)
It is possible to provide an extrusion molding machine that can perform these operations with peace of mind.
