<p>An apparatus or system for the aligning and severing of fabric webs which have a thickness differing in the longitudinal direction, for example a terry cloth fabric with napless lanes extending crosswise to the longitudinal direction and lanes which have a nap arranged in an alternate pattern comprises aligning means which cooperate with the boundary areas between adjacent lanes of the fabric web and which extend crosswise to the web pull off direction. A cutting device is arranged crosswise to the web pull off direction at a location after the aligning means and braking means in the form of individually adjustable brake elements which extend across the width of the fabric are arranged between the aligning means and the reel supply of the fabric material. The aligning means includes an alignment device which may be positioned in contact with the fabric for example at the location of the fabric which does not have any nap and the alignment means includes a plurality of individual shoes which are biased into engagement with the fabric at spaced lateral locations along the width. The individual shoes are supported by a member that is guided by a carriage which moves in the pull off direction with the shoes biased into engagement with the fabric material. Simultaneously with the engagement of the alignment means individual braking elements are moved into engagement with the fabric between the alignment means and the reel supply and these individual braking elements are adjusted to provide a braking action on the fabric which facilitates the straightening of the fabric along with the movement of the engagement shoes in the napless section toward the boundary line of the section which has the naps.</p> |
