Apparatus for producing rollers with elastic silicone-based material

Abstract

An apparatus for producing rollers covered with layers of elastic silicone-based material, including: a base frame; a hollow box-like cylindrical support-mold rotatably mounted on the base frame about a longitudinal axis,of the support-mold; a device for rotating the support-mold about its longitudinal axis; a hollow prepared and coverable cylindrical perforated supporting structure which is removably insertable coaxially and snugly inside the support-mold so as to provide a perimetric seal between opposite ends of the supporting structure and the support-mold and so as to define a sealed interspace between the outer surface of the supporting structure and the inner surface of the support-mold; slides mounted on the base frame; a device, slidably mounted on the slides, for introducing elastic silicone-based material inside the supporting structure such that upon rotation of the support-mold the elastic silicone-based material travels through the perforated supporting structure from the inside of the supporting structure to the interspace so as to form a covering about the supporting structure; a device for heating and curing the covering at the support-mold for forming a covered roller; and elements for removing the covered roller from the support-mold.
