In this cooking extruder the nozzle head (12) is disposed in a nozzle plate (10) and the passage (34) through which the material for the envelope body is supplied extends at an angle to the axis of a filling tube (42) through which the filling material is introduced into the extruded envelope body.

In this cooking extruder the nozzle head (12) is disposed in a nozzle plate (10) and the passage (34) through which the material for the envelope body is supplied extends at an angle to the axis of a filling tube (42) through which the filling material is introduced into the extruded envelope body. When clogging occurs during production the filling tube (42) can be withdrawn from the nozzle head (12) and replaced by a new filling tube. The front end of the filling tube (42) is led between forming rolls (66, 68) and serves as abutment for said rolls. This makes it possible to form the surface of the envelope body with a pattern or bake said surface locally or over the entire periphery. In the nozzle head (12) a baffle plate (30) is disposed with the aid of which a uniform distribution of the material supplied for the envelope body may be achieved. An annular space between a lining tube (28) in the hollow mandrel (22) and the filling tube (42) may be subjected to suction extraction.

A cooking extruder head for use with a cooking extruder, having a source of envelope material and a source of filling material, said cooking extruder head comprising: a nozzle plate having opposed forward and rearward sides, said nozzle plate being characterized by forward and rearward apertures offset from one another and extending into the respective forward and rearward sides of said nozzle plate, and a passage extending between said forward and rearward apertures and providing communication therebetween, said nozzle plate being connectable to said source of envelope material at the rearward aperture therein, such that the envelope material is deliverable to the forward aperture of said nozzle plate through said passage; and a filling tube connectable to said source of filling material and adjustably and removably mounted to said nozzle plate and extending entirely therethrough from the rearward side to the forward side thereof, said filling tube being substantially aligned with and extending from the forward aperture therein and being angularly aligned to said passage, whereby the amount of extension of the filling tube from the forward side of said nozzle plate is selectively adjustable and whereby the filling tube is selectively removable from said nozzle plate.
