Abstract
The present invention relates to an automatic elastomer extrusion apparatus and method. An apparatus 400 for in-situ extrusion of an elastomeric coating 410 on a profiled helical surface 450 can include a template (100, 200) forming a gap between the profiled helical surface 450 and an adjacent profiled helical surface (102, 202) of a template (100, 200) itself to extrude an elastomer therethrough. A tracking mechanism 302 and/or carriage 300 can allow a template to follow the contours of the profiled helical surface 350. The apparatus can include means for providing relative movement between the profiled helical surface and the template. The apparatus (500, 600) can include a cleaning module (502, 602), an adhesive application module (504, 604), an elastomer deposition module (506, 606), and/or a curing module (508, 608). Each module can further include a template (100, 200) and/or a tracking mechanism 302.
