Abstract
An apparatus handles and transports long strip materials between a first processing section, with a first transporting roller assembly which transports a long strip material lengthwise at a first speed therein, and a second processing section with a second transporting roller assembly which transports the long strip material lengthwise at a second speed different from the first speed, the strip material passing through a reservoir section with a guide member disposed between the first and second processing sections for temporarily reserving the long and narrow strip material therein in the form of a loop. The long strip material handling apparatus includes a speed changing mechanism for changing the speed of lengthwise transportation of the long strip material to the first or second speed before the leading end of the long strip material passes through the second transporting roller assembly when the second transporting roller assembly first threads the leading end of the long strip material, and a leader sensor for detecting the leading end of the threaded long strip material to provide a signal in response to which the speed changing mechanism is deactuated.
