System for automatic joining and rolling up of cord strips

摘要

Apparatus for automatically joining and winding up cord strips for tires includes a stationary table with a joining device movably mounted above the stationary table. The joining device comprises a carriage carrying a spring loaded roller which is spring loaded in a downward direction toward the stationary table, and a pair of pulleys located behind the spring loaded roller, relative to the direction of movement of the carriage, the pulleys being obliquely mounted at an angle toward each other for engaging respective ends of cord strips to be joined to draw the respective ends together when the roller and pulleys are rolled over the ends of the cord strips to be joined during movement of the carriage. The spring loaded roller presses down the ends of the cord strips to be joined on the stationary table and the pulleys draw together the pressed down edges of the cord strips to join them by the adhesiveness of the strip edges combined with the pressure imparted thereto by the obliquely mounted pulleys.
