  • Patent number: 10967545
    Abstract: A profiling calender includes an intermediate roll, a lower roll, and a pair of intermediate lugs. The intermediate and lower rolls are separated by a distance defining a height of a second profiling nip. The intermediate lugs are situated at ends of the intermediate and lower rolls and include two quarter-circle bearing surfaces that meet at the second profiling nip. Each end of the intermediate roll or each end of the lower roll is equipped with a collar fastened to the roll and positioned between the roll and a quarter-circle bearing surface of a corresponding intermediate lug. The collar enables a radius of the roll to be increased by a height equal to the separation distance in order to improve an appearance of edges of a profiled element produced by the calender.

  • Patent number: 10967546
    Abstract: A calender is provided for profiling a rubber mixture intended for the manufacture of tire casings, the calender having three rotating rolls, the intermediate roll and the lower roll being separated by a second distance in the vertical plane, this second distance defining the height of a second profiling nip, wherein the calender includes a table for separating the profiled mixture that is positioned downstream of the second profiling nip, making it possible to avoid cohesion defects manifested by the appearance of cracks and fissures in the profiled element leaving the calender.
