Abstract: A device for producing meat products by stuffing meat mass in a double casing made up of a film and a net, has a stuffing tube with a diameter, a mechanism for passing the meat mass through the stuffing tube and into the double casing and a mechanism for shaping the film into a cylinder that is adapted to the diameter of the stuffing tube, the shaping mechanism forming longitudinal folds for allowing radial expansion of the cylinder when the cylinder is fed with meat mass through the stuffing tube by unfolding the folds.

Abstract: The current invention involves a universal fishing bait fundamentally comprised of a matrix of fibrous collagen made up into any shape or design capable of attracting fish, that is 100% biodegradable and innocuous, that has physico-chemical properties that confer it with the capacity to accommodate liberate and diffuse attractant substances, and whose physico-mechanical properties confer it a soft and flexible texture, as well as making it resistant to breakage. Likewise, the invention outlines a procedure to prepare such a bait, and a precursor paste employed in the preparation, as well as the use of fibrous collagen in the preparation of said universal fishing bait.

Abstract: Based on a conventional installation including a stuffing-portioning machine (1) and a fast clipper (2), duly synchronised, between which is established a shaping device (3) that converts the film (5) meant to wrap food products that is supplied in the form of a coil into a tubular element that can be coupled to the stuffing tube (3), on which is coaxially mounted a second tube (8) bearing an external casing (9) based on a tubular net, the invention consists of using tubes (4) and (8) with a small diameter, much smaller than that of the finished product, so that the film (5) is adapted to the tube (4) after the former is profusely folded longitudinally, while the small diameter of the tube (8) allows the multilayer shirring of the tubular net (9), using the pressure provided by the pumping system of the stuffing machine (1) to achieve the radial expansion of the film (5) and the tubular net (9) to obtain the final diameter of the finished product, which will vary according to the speed with which it is separa

Abstract: Incorporates buckets (3) open on their top in which the meat pieces are loaded, moving on traction device (4) that execute a step by step motion towards the feeding area located between the piston (1) and the body of the stuffing machine (2), where the meat piece is pushed by the piston (1) towards the body of the stuffing machine (2) for compacting and subsequently wrapping it. The buckets (3) have open front and rear faces to facilitate the run of the piston (1) and the exit of the meat piece towards the body of the stuffing machine (2). In addition, a device is provided for facilitating the centered position of the bucket with respect to the position of the piston (1) in the feeding area.
