Abstract
A device including two heads which may be positioned at an applying station to apply parallel lengths of elastic reflex-light reflective strip material in an unstretched condition around the circular outer surface of a tire casing rotated past the station. Each head includes a vacuum column which supports a supply length of the strip material adjacent the applying station so that the strip material at the applying station will be under essentially no tension; and a tape drive mechanism which removes and drives away a protective liner from the strip material, drives the strip material toward the vacuum column at a variable rate to maintain a supply length of the strip material in the vacuum column and has a novel self adjusting feature that insures equal driving rates for the strip material and liner. The device also includes means for sensing the including a novel brake and chain assembly for positioning the strip material in a predetermined position with respect to its leading end so that it may be severed to provide a predetermined overlap of the ends of the strip material around the tire casing.
