Total Claims: 6
Claim 1
Independent Claim
168 words
A tear tape applicator adapted to be mounted on apparatus for making sheet material comprising an elongated body member, mounting means rotatably supporting a roll of tear tape at one end of the body member, a guide member mounted on said body member adjacent the other end thereof, a guide roll pivotally mounted adjacent said other end, an arm pivotally mounted from said other end, a roller pivotally mounted on said arm, said tear tape extending from said mounting means through said guide member over said guide roll to said roller which presses the same against the sheet material, spring biasing means normally pivoting said arm in a direction to press said roller and said tape against the sheet material, bracket mounting means depending from said body member for detachably securing said applicator to the apparatus for making sheet material, and means for selectively varying the cOmpression in said spring biasing means whereby the pressure applying relation of said roller against said sheet material may be varied selectively.
