ABSTRACT:
An apparatus and methods are provided for dancingly controlling tension in a web of fabric such as for disposable garments. The apparatus preferably includes a dancer frame, a first set of a plurality of spaced-apart fabric guides connected to the dancer frame, a track connected to the dancer frame, and a tension yoke mounted for slidably following the he track. The tension yoke preferably includes a second set of a plurality of spaced-apart fabric guides positioned for slidably following the movement of the tension yoke when following the track. The apparatus also preferably includes a weight tension control assembly connected to the tension yoke for weightingly controlling the tension applied from the tension yoke to a web of fabric positioned thereon to thereby readily increase and decrease the tension applied to the web. A method of controlling tension in a web of fabric preferably includes positioning a web of fabric on first and second sets of a plurality of spaced-apart fabric guides, moving the web of fabric across the first and second sets of a plurality of spaced-apart fabric guides, and dancingly moving at least one set of the first and second sets of a plurality of fabric guides during movement of the web of fabric across the first and second sets of a plurality of spaced-apart fabric guides.
