Problems solved by technology
[0003] Disadvantages: The rubber-covered cord produced by the calender is prone to bending of the jumper, tightness on both sides and looseness in the middle, so that the tension of the cord cannot be uniform
[0005] At present, although the fiber cord produced by steel wire calendering has no weft and is evenly arranged, it is difficult to control the tension, and it is impossible to accurately control the tension of each cord.

Embodiment Construction
[0025] combined with Figures 1 to 2 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0026] Calendering refers to the process of making the mixed rubber into a film and the skeleton material into a semi-finished tape on the calendering equipment.
[0027] Gluing refers to the process of pressing a film of a certain thickness on the fabric under the pressure of the upper and lower rollers of the calender on the film.
[0028] The entire linkage line of the special calendering method for the fiber cord carcass includes the pre-calendering section, the calendering machine section, and the post-calender...

The invention discloses a special calendering method for a fiber cord carcass. An adopted framework material is a single fiber cord; the special calendering method for the fiber cord carcass comprises the steps that the single fiber cord is fed into a calender workshop section from a calendering front section, and a glue supply assembly line supplies glue to the calender workshop section; fiber cord fabric is calendered by the calender workshop section; the thickness and width of the fiber cord fabric are detected; and the fiber cord fabric which is output by the calender workshop section and meets the set value enters a calendering rear end to be stored and coiled. According to the fiber cord fabric produced by the special calendering method for the fiber cord carcass, the uncoiling tension of each cord is independently controlled, so that the tension of each cord is more uniform during calendering and glue coating, the density of the cords with glue is more uniform, the strength of a tire is improved, and the safety of the aircraft tire is improved.
Description
technical field [0001] The invention relates to the field of tire fiber cord production, in particular to a special calendering method for a fiber cord carcass. Background technique [0002] In the prior art, the tire fiber cord is produced by a calendering method, and the calender is used in the production process to produce a rubber-coated fiber cord with a width of about 1450 mm to produce a rubber-coated cord. [0003] Disadvantages: The rubber-covered cord produced by the calender is prone to bending of the jumper, tightness on both sides and looseness in the middle, so that the tension of the cord cannot be uniform. There are two main reasons for this. One is that the raw material fiber cord is a wide cord woven from warp and weft threads. There will be uneven tension of the weft threads and uneven stretching of the warp threads. It is impossible to achieve independent control of the tension of each cord leading, resulting in uneven cord tension during calendering and...
