Abstract: The present disclosure relates to an arrangement in a tire retreading rolling machine including a structure composed of a lower frame (Q) provided with adjustable feet (P) and one column (C) on one of its vertices. Column (C) has on its outer side a motoreducer set (MR) which rotates a hub (CB) positioned on the column inner side. A bearing (M) held to column (C) supports the hub (CB) shaft, on which the tire to be processed is mounted. The rolling device mounted on the frame (Q) comprises arms (1) with end rolls (2), on which the tire is rested on the wheeling position. The rolls (2) press the new tread against the tire carcass, expelling the air that may have been trapped. The arms (1) are centrally pivoting in transversal gears (3), by the action of cylinders (4), allowing to get rolls (2) closer or farther to/from the new tread applied to the tire carcass. Secondary rolls (5) with semi-spherical shape, are positioned on the arms ends (1) from the outside, and close to the main rolls (2), so as to exert pressure also on the tread sides, next to the tire shoulder. A horizontal spindle (6) is driven by a motor (7) and reducer (8) set, and is intended to move the arms (1), making the secondary rolls (5) exert pressure against the tire shoulders. The gears (3) are mounted over the bearings (9) sliding on the machine busbars (10), causing the rolls (2) and the secondary rolls (5) to exert pressure throughout the tread, including the shoulders area.

Abstract translation: 本公开涉及一种轮胎翻新滚轧机中的布置，其包括由在其顶点之一上设置有可调节支脚（P）和一列（C）的下框架（Q）构成的结构。 柱（C）在其外侧具有使定位在柱内侧上的轮毂（CB）旋转的制动器组（MR）。 保持在塔（C）上的轴承（M）支撑轮毂（CB）轴，在该轴上安装有待加工的轮胎。 安装在框架（Q）上的滚动装置包括具有末端辊（2）的臂（1），轮胎在其上搁置在转轮位置上。 辊（2）将新的胎面压靠在轮胎胎体上，排出可能已经被捕获的空气。 臂（1）通过气缸（4）的作用在横向齿轮（3）中居中枢转，允许使辊（2）更接近或远离施加到轮胎胎体的新胎面。 具有半球形的次级辊（5）从外部位于臂端部（1）上并靠近主辊（2），以便在轮胎胎肩侧面附近施加压力 。 水平主轴（6）由电动机（7）和减速器（8）驱动，并且旨在移动臂（1），使得副辊（5）对轮胎胎肩施加压力。 齿轮（3）安装在滑动在机器汇流条（10）上的轴承（9）上，使辊（2）和次辊（5）在整个胎面（包括肩部区域）施加压力。
