Abstract:

Apparatus for embossing web material such as a heated thermoplastic web material comprises first and second embossing members each having a resilient embossing surface, and means mounting the embossing members for relative movement to define a roll nip between them. The resilient surface of the first embossing member has a primary embossing pattern thereon and is of harder durometer than the resilient surface of the second embossing member. Both resilient surfaces are soft enough to be temporarily deformed in the roll nip to press the web material between them into surface conforming contact with the primary embossing pattern. The temporary deformation also helps to expel air from between the web material and the primary embossing pattern to insure surface conforming contact of the web to the embossing pattern. A secondary embossing pattern is provided on the resilient surface of the second embossing member and is of lesser depth than the primary embossing pattern. The temporary deformation assists in providing full contact with both patterns.

Abstract:

A horizontal door assembly is provided with pivotal counter balancing spring comprising an upper cylinder and a mating lower cylinder to force the cover of the door to an open position when the door assembly is unlocked wherein the upper cylinder of the counter balancing spring is configured to reduce the forces of the spring on the pivot points of the counter balancing mechanism thereby increasing the life of the counter balancing mechanism. In a preferred embodiment, the counter balancing spring mechanism is made of plastic and has an ear at the upper end thereof with an elongated slot opening the slot having a longitudinal axis substantially parallel to the longitudinal axis of the cylinder for mating with a pin inserted in an opening in a yoke bracket attached to the lower side of the cover. When the cover is in the closed position, the bottom of the cover rests on the upper surface of the ear and the pivot pin is positioned intermediate the elongated slot opening thus reducing the spring forces on both the pivot point of the counter balancing spring mechanism and on the spring mechanism.
