Abstract

An apparatus for applying stripes on a carrier to a moving web includes a first drive to advance the carrier continuously from an unwind reel to a take-up reel at a generally constant speed. A nip is intermediate the unwind reel and the take-up reel through which the carrier and the web pass. The nip applies the stripes to the web. A reciprocating shuttle is moveable back and forth along a generally linear path. The shuttle includes a first set of spaced rollers thereon adjacent one end thereof and a second set of spaced rollers thereon adjacent an opposite end thereof. A first stationary set of spaced rollers is associated with the first set of rollers. The first stationary set of spaced rollers is positioned adjacent one end of the path and intermediate the unwind reel and the nip. A second stationary set of spaced rollers is associated with the second set of rollers. The second stationary set of spaced rollers is positioned adjacent an opposite end of the path and intermediate the nip and the take-up reel. The carrier alternately winds around the rollers of the first set of spaced rollers and the first stationary set of spaced rollers as the carrier travels from the unwind reel to the nip. The carrier also alternately winds around the rollers of the second set of spaced rollers and the second stationary set of spaced rollers as the carrier travels from the nip to the take-up reel. A second drive reciprocates the shuttle along the linear path. The shuttle is driven in a manner so that the carrier intermittently moves through the nip even though the carrier is advanced continuously by the first drive.
