ABSTRACT:
An apparatus for fixing the leading edge of a second rolled web to a point at or near the trailing edge of a first rolled web. The present invention is an improvement over the disclosure of U.S. Pat. No. 3,837,954, issued Sept. 24, 1974, wherein the leading edge of a second roll was adhered to a transfer roll while the trailing end of the first web was contacted by a suitable base roll. In this improvement, a fluid operated carriage forms a resiliently braked loop following the base roll and permits the web at the base roll to slow as needed to pick up the second web while not diminishing the speed of exiting of the web from the transfer apparatus. The carriage is moved in one direction to compensate for this change in relative speeds. The carriage is then caused to move in the opposite direction to generate a smoothly increasing force resisting such yielding then progressively increasing the pull on the web and its speed of withdrawal from the second roll. Thus, adherence between the webs is completed by the time tension is placed onto the point of adherence for the acceleration of the second roll.
