Abstract
A process and plant for making wadding or fiber flocks starting from a padded textile product, in which processing is carried out together and simultaneously of all the textile materials forming the same starting padded product. The process includes defibering and tearing, together and simultaneously, of fabric and wadding fibers forming the padded textile product, with formation of a single wadding layer, subsequently transformed into wadding flocks.

A process for making a wadding starting from a padded textile product, either recycled or resulting from surplus production, comprising defibering and tearing, together and simultaneously, of fabric and wadding fibers forming said padded textile product, with formation of a single wadding layer, subsequently transformed into wadding flocks, wherein:
- a) said textile product is processed in a compression station (4), in which said textile product is crushed and compressed into a crushed and compressed product;
- b) the crushed and compressed product obtained from step a) is processed inside a defibering and tearing station (6), which carries out a defibering and tearing treatment of all materials of said crushed and compressed product together and simultaneously by means of two pairs (7,8) of rotating plates (9,10), each rotating plate of said two pairs of rotating plates being provided with needles (11,12) to obtain a fibrous material;
- c) the fibrous material obtained from said step b) is subsequently processed in a subsequent transformation station (13) for transforming said fibrous material into a thin layer of parallelized fibers which substantially form a wadding textile material layer by means of two pairs (14,15) of cylinders (16,17), each cylinder of said two pairs of cylinders being provided with needles (18,19);
- d) the wadding textile material layer obtained in step c), from which the wadding flocks are obtained, is torn and opened in a subsequent air circulation station (21).
A plant for making wadding starting from a padded textile product (1) comprising:
- a defibering and tearing station (6) with two pairs (7,8) of rotating plates (9,10), wherein each pair of plates of the two pairs of rotating plates is formed of an upper plate (9) and a lower plate (10) with needles (11,12) with different sizes and density and in a staggered arrangement between the needles (11) of the upper plate (9) and the needles (12) of the lower plate (10) and with mutually opposing rotation, adapted to form a fibrous material,
- a downstream transformation station (13) for transforming said fibrous material into a thin layer of parallelized fibers which substantially form a wadding textile material layer, wherein said transformation station (13) is provided with two pairs (14,15) of cylinders (16,17), which transform the fibrous material prepared in the defibering and tearing station (6) into a layer of parallelized fibers, wherein each pair of cylinders of the two pairs of cylinders (14,15) is composed of an upper cylinder (16) and a lower cylinder (17), with mutually opposite directions of rotation, wherein said upper cylinder and said lower cylinder bear needles (18,19) respectively, with different length and density, fixed on supports arranged in a staggered arrangement between the needles (18) of the upper cylinder (16) and the needles (19) of the lower cylinder (19),
- a downstream air circulation station (21), in which the wadding textile material layer, from which the wadding flocks are obtained, is torn and opened when the air circulation station is in use.
