A cooling tool (1) for a food or an animal feed extruder (E), the cooling tool has: an inlet end (3) at which extrudate (4) can be led into the cooling tool (1); an outlet end (5) where the cooled extrudate can be discharged; an extrudate flow channel (6) extending from the inlet end to the outlet end; and at least one coolant flow channel (7a, 7b, 7b′) connected to the extrudate flow channel in a heat-transmitting manner. In a cross section (X-X) along the primary flow direction (8), the extrudate flow channel is substantially formed as a ring section; and the outer wall (9) of the extrudate flow channel (6) is formed at least from first and second segments (10, 11). The first and second segments are connected to each other by mechanical connection elements (12). The cooling tool is suitable for wet texturing of food and animal feed.

A method for controlling the thickness of a continuous elongated element made of elastomeric material, applied according to coils wound on a forming support, includes: advancing a head end of the continuous elongated element toward the forming support; subjecting, during the advancement, the continuous elongated element to a first stretching with a first stretch coefficient before applying on the forming support; and subjecting, during the advancement, the continuous elongated element to a second stretching with a second stretch coefficient during the application on the forming support. During the first stretching, a span of the continuous elongated element adjacent to the head end is stretched with a supplementary stretch coefficient greater than the first stretch coefficient, in a manner so as to confer, also to the span adjacent to the head end, a stretch and a section similar or substantially equivalent to those of the rest of the continuous elongated element.

A screw for a plasticating apparatus has one or more helical flights. A portion of the screw has a plurality of advancing grooves arranged in a noncontinuous helix cut in the screw. The advancing grooves are dimensioned to receive material therein as the material is conveyed through the barrel. The screw has a plurality of noncontinuous cross-cut grooves traversing one or more of the advancing grooves. The cross-cut grooves have a second helix angle greater than the first helix angle and less than ninety degrees; and/or one or more of the cross-cut grooves have a third helix angle of about ninety degrees.
