ABSTRACT:
To make decorated strands of pasty products, a pasty material is continuously extruded from a nozzle integral with a mobile support disposed above a continuously moving conveyor belt. The apparatus thus includes a conveyor belt adapted for continuous movement, a mobile support disposed above the conveyor belt, at least one extrusion nozzle integral with the mobile support, at least one source for providing a continuous supply of pasty product to each nozzle and means adjacent an edge of the conveyor for transmitting movement to the support for moving it in one plane while keeping it in the same orientation in space for providing a repetitive curved trajectory for each extrusion outlet orifice. In operation, the extrusion nozzles, having their outlet orifices above the conveyor belt, are positioned at an angle of from 60.degree. towards the direction of movement of the conveyor belt to being parallel with the belt. The relative movements of the nozzle and the conveyor belt are such that a continuous, regularly wound strand is formed on the conveyor belt.
