Pinching-shaping device, and system for continuous production of foods products co-extruded in pouch form

A pinching-shaping device, comprising two tools, each tool being cylindrical, each tool having a central axis around which the tool is rotatable, and each tool having an outer periphery,

• wherein the two tools are arranged such that the respective central axes of the two tools are substantially parallel and the respective outer peripheries of the two tools are applied tangentially against each other to pinch-shape a strand inserted tangentially between the two tools upon rotation of the two tools,
• wherein each tool is provided with blades which:
• radially protrude from the outer periphery of the tool, and
• are successively distributed around the central axis of the tool,
• wherein each blade of each tool has a free edge which:
• is radially opposite to the central axis of the tool, and
• is provided with a pinching surface extending between first and second ends of the pinching surface, which are opposite to each other along the central axis of the tool, the respective first ends of the pinching surfaces of each tool being all located on a same first axial side of the tool, while the respective second ends of the pinching surfaces of each tool are all located on a same second axial side of the tool, opposite to the first axial side along the central axis of the tool,
• wherein the pinching surface of each blade of each tool runs inclined with respect to the central axis of the tool between the first end and the second end of the pinching surface, and
• wherein the blades of each tool are distributed, alternatively along the outer periphery of the tool, into at least one first blade and at least one second blade, the first end of the pinching surface of the at least one first blade being radially further from the central axis of the tool than the second end of the pinching surface of the at least one first blade, and the second end of the pinching surface of the at least one second blade being radially further from the central axis of the tool than the first end of the pinching surface of the at least one second blade, whereby each time one blade amongst the blades of a first of the two tools is radially interposed between the two tools upon rotation of the two tools, said one blade of the first tool is radially aligned with one blade amongst the blades of the second tool so that the pinching surface of said one blade of the first tool and the pinching surface of said one blade of the second tool are inclined in a complementary manner to each other and pinch therebetween a strand inserted tangentially between the two tools.
