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.

Dependent claims

An apparatus for preparing decorative pastry products comprising:

a conveyor belt for providing a surface to be advanced and to accept deposit of extruded pastry material;
a mobile support disposed above the surface of the conveyor belt to be advanced extending transversely with respect to a direction of movement in which the surface of the conveyor belt is to be advanced;
at least one extrusion nozzle and means associated with each extrusion nozzle for securing each extrusion nozzle to the mobile support, each extrusion nozzle terminating in an extrusion nozzle outlet orifice positioned above the surface of the conveyor belt to be advanced and each securing means providing for inclining and adjusting the inclination of each extrusion nozzle, in operation, from being parallel with to being inclined at an angle of up to 60 .degree. towards and in the direction in which the surface of the conveyor belt is to be advanced;
at least one source for providing a supply of pastry product to each extrusion nozzle for extrusion from each extrusion nozzle outlet orifice onto the surface of the conveyor belt to be advanced;
and
means adjacent an edge of the conveyor belt for transmitting movement to the mobile support for revolving the mobile support in one plane while keeping the mobile support in the same orientation in space for providing each extrusion nozzle outlet orifice with a repetitive curved trajectory for, in cooperation with advancing movement of the surface of the conveyor belt to be advanced, forming a continuous wound strand of pastry material.
