242, Winding, Tensioning, or Guiding,

551+, for web uniting devices in which the webs are carried on reels. The patents are classified in Class 242, where means are recited for bodily displacing the web carrying reel even though adhesion may be claimed. Mere rotation of the reel for web feed, even though reciting speed control, tension control or other perfecting features for the web feed are not sufficient for Class 242 where the reel rotates at a fixed position and laminating is recited.
