Abstract

Head for extrusion of a tubular structure suitable to be shaped for blowing including either two channels with entrance with a 180 degrees drop and with a circumference extension that can grow up to 360 degrees each or four channels with a 90 degrees drop and with a circumference extension that can grow up to 180 degrees each in exit extension. Each channel includes a nozzle that can extrude material different from the one that can flow into the channels. The invention allows to reduce costs and simplify the operation.
