Abstract: Adhesive is applied to a web by way of a printing plate and reverse enclosed doctor blade so as to apply the adhesive in selected locations thereby minimizing the amount of adhesive applied in order to decrease the stiffness of the resultant multi-ply web. The amount of adhesive build up on the embossing rolls due to the adhesive bleeding through the web material is minimized and the embossing rolls are permitted to clean themselves in that the adhesive application is carried out so that adhesive is not applied to the web material adjacent portions of the embossing roll on successive rotations of the roll. By doing so, portions of the backup roll which support the web where adhesive was previously applied are permitted to selfclean by allowing the adhesive which has bled through the web and collected on the backup roll to dry and flake off prior to adhesive again being applied to the web adjacent such region.

Abstract: Containers are conveyed through an oven on a conveyor to cause a foamable material on each container to foam and become a heat insulative layer. The containers are supported on respective holders of the conveyor, which prevent the containers from contacting one another. Preferably, the holders support the containers loosely, to enable the containers to wobble relative to the holders under the influence of oven air currents and conveyor vibration. The holders thus do not make contact with any given point on their respective containers for a time period that is sufficient to enable the holders to draw enough heat away from the container to adversely affect the foaming operation. The containers are conveyed in single file, along a serpentine path through the oven.

Abstract: A toilet tissue dispensing mechanism includes a unit formed by a pair of parallel vertical walls. Each wall includes vertically spaced openings arranged such that the openings of each wall are in vertically staggered relationship with the openings of the other wall when the movable wall is closed. Each opening has a roll-mounting structure associated therewith, whereby each wall is capable of concurrently dispensing a pair of tissue rolls. Each roll-mounting structure includes a shield mounted for swinging movement between open and closed positions for securing the rolls in their respective openings. To convert such a mechanism to a dispenser which dispenses rolls sequentially rather than concurrently, the shields are swung to their open positions, and adapter plates are positioned against inside surfaces of respective ones of the walls to cover the openings therein. The plates are pressed against the respective walls by edges of the shields.
