    摘要： A device for joining ends of material strips of rubber or plastic materials with rubber properties, wherein the ends to be joined have areas of reduced wall thickness and wherein the end cut first is stretched shortly before joining the two ends, includes a plurality of force-transmitting elements positioned adjacent to one another transverse to a longitudinal direction of the material strip at a forward end thereof and acting on one face of the material strip. At least the force-transmitting elements positioned at the areas of reduced wall thickness of the forward end are movable in the longitudinal direction of the material strip for stretching the forward end of the material strip at least within the areas of reduced wall thickness.

    摘要： An apparatus joins opposite ends of a tread on a rotary drum in a tire making machine. Besides the rotary drum, the apparatus includes a conveyor having two lateral endless loops and a guide in the form of rollers interposed between the loops. The conveyor is disposed upstream of the rotary drum. Clamping mechanisms are provided to clamp the respective sides of the tread at a rear end thereof to the endless loops of the conveyor, respectively. A tread placed on the endless loops of the conveyor is maintained in relative position by the guide. The actual length of the tread on the conveyor is measured. The front end of the tread is adhered to the rotary drum and the opposite sides of the tread at the rear end thereof are clamped to the conveyor. The conveyor and drum are then driven at appropriate speeds based on the length of the tread to cause the ends thereof to be joined on the drum. Movable grippers can be provided to stretch the rear end of the tread at the sides thereof into abutment with the front end.

    摘要翻译： 一种装置将胎面的相对端连接在轮胎制造机中的旋转鼓上。 除了旋转滚筒之外，该装置还包括具有两个横向无端环的传送器和一个设置在环之间的滚轮形式的引导件。 传送带设置在旋转滚筒的上游。 提供夹紧机构，用于将其后端的胎面的相应侧分别夹紧到输送机的无端环。 放置在输送机的无端环上的胎面由引导件保持在相对位置。 测量输送机上胎面的实际长度。 胎面的前端粘附到旋转鼓上，并且其后端处的胎面的相对侧被夹紧到输送机。 然后基于胎面的长度以适当的速度驱动输送机和滚筒，使其端部在滚筒上接合。 可以设置可移动的夹持器，以使其在其侧面处的胎面的后端部与前端邻接。

    摘要： In a cylindrical tire forming member building method or apparatus, after the front end portion of a belt-shaped material is pressed against the drum, the belt-shaped material is wound on the drum while being centered, and with the central portion of the rear end portion of the belt-shaped material pressed against the drum with a robot hand, both edge portions of the rear end portion of the belt-shaped material are elongated longitudinally and pressed against the drum with the robot hand, so that the front and rear ends of the belt-shaped material are butt-joined without forming a gap therebetween or without being overlapped.
