摘要： A stretching apparatus of fibre tows in a pressurized steam environment includes an elongated stretching chamber having a generally rectangular section of a low height, within which the tows are treated with saturated or overheated steam at high temperature and pressure and simultaneously undergo a mechanical stretching operation. The stretching chamber has a width sufficient to house multiple tows mutually flanked in a running plane and is formed within a stretching chest made of aluminum. The stretching chest is housed in a supporting structure, having a higher structural rigidity than the stretching chest, which includes a plurality of contact elements apt to determine a predefined position of the stretching chest with respect to a direction perpendicular to the tow running plane and to allow a limited mobility of the stretching chest in the other two mutually perpendicular directions which lie in the plane, length and width respectively.

摘要： A stretching apparatus of fibre tows in a pressurized steam environment comprises a plurality of stretching chests (1) and associated supporting structures (3, 4, 6) arranged side by side, at the same level, on a holding frame. The stretching chests (1) are each formed by two opposed metallic half-chests (1b, 1t), delimiting a stretching chamber (2). The stretching chamber (2) has a generally rectangular section of a low height and opens outwards in correspondence of the two transversal edges of the stretching chest (1) through tow entry and exit openings. Inside the stretching chambers (2) the tows are treated with saturated or overheated steam at high temperature and pressure and simultaneously undergo a mechanical stretching operation.

摘要： A support element for a feed roller for a fibre material, preferably a precursor fibre, to be used in an oxidation or carbonization line for producing carbon fibres, including a base provided with means for attachment to a structure or frame of the oven, a support ring coupled with the base and having at least one passing-through opening for receiving one end of the feed roller, and adjustment means operatively interposed between the base and the ring, and configured to move the position of the ring with respect to the base along at least one adjustment direction, transverse to a central axis of the opening, in order to adjust the position of the ring as a function of the deformations of the roller.

摘要： Compact module for wet spinning of chemical fibres of the type comprising a spinning head (F) of 2-8 tows (S), each one consisting of a plurality of continuous filaments, relative supply pumps (P) of the spinning solution, a coagulation tank (V) containing a coagulation solution, and a plurality of drive rollers (2) and respective idle diverter rollers (3) which determine a zigzag path of the tows (S) downstream of the spinning area, in the rectilinear lengths of which liquid-based treatments are carried out on said tows (S). The rectilinear lengths of said zigzag path are horizontal and said liquid-based treatments on the tows (S) are carried out in horizontal treatment trays (4) of the spillway type.
