Patent ID: 7690548

Claim:
An apparatus for contacting a web of indefinite length, comprising: a frame include a pair of opposed side plates; a rotatable anvil supported by the side plates, wherein the anvil has two degrees of freedom including rotation about a rotational axis of the anvil and a lateral position adjustment of the anvil relative to the side plates; a rotatable horn supported by a horn mount that is slidably connected to the side plates, wherein the horn has three degrees of freedom including rotation about a rotational axis of the horn, translational movement towards or away from the anvil, and a tilt adjustment towards or away from the anvil; a horn lift assembly for driving the translational movement of the horn and for setting the tilt between the horn and anvil including; a pair of link arms pivotally connected to the horn mount, wherein at least one connection point between the link arms and the horn mount is adjustable for adjusting the tilt of the horn relative to the anvil; a pair of gear together pivot arms connected to the link arms, a pair of pivot shafts connected to the frame and the pivot arms, wherein when a force generator is actuated the pair of link arms raise the pair of pivot arms causing the translational movement of the horn towards or away from the anvil.
