  • Publication number: 20070107863
    Abstract: An improved process for making sheet from a fibrous furnish includes: depositing the furnish on a foraminous support; compactively dewatering the furnish to form a nascent web; drying the web on a heated cylinder; creping the web therefrom and throughdrying the web to a finished product. The microstructure of the web is controlled so as to facilitate throughdrying. The product exhibits a characteristic throughdrying coefficient of from 4 to 10 when the airflow through the sheet is characterized by a Reynolds Number of less than about 1. The novel products of the invention are characterized by wet springback ratio, hydraulic diameter and an internal bond strength parameter.

  • Patent number: 7182289
    Abstract: Apparatus for dispensing paper from rolls which feeds continuously, roll to roll, and does not require extra procedure to bring stub roll into position. The apparatus holds and positions at least first and second rolls of paper with respect to each other, dispensing paper from the first and second rolls simultaneously when the first roll reduces to a predetermined diameter of paper, positioning the depleted first roll for replacement without the necessity of removing the second roll; and dispensing from the second and replacement rolls simultaneously when the second roll reduces to a predetermined diameter of paper. The apparatus also has a proximity sensor, which senses when a hand is placed near the dispenser, and thereupon dispenses a set amount of towel. The dispenser dissipates static charges to a local ground such as a high impedance wall surface on which the dispenser is mounted.

  • Patent number: 7182288
    Abstract: A dispenser for rolled absorbent web material is disclosed. A carriage is rotatable between at least two orientations. The carriage includes a first roll holder, which holds a first roll of absorbent web material in a primary position when the carriage is in a first orientation and in a secondary position when the carriage is in a second orientation, and a second roll holder, which holds a second roll of absorbent web material in the secondary position when the carriage is in the first orientation and in the primary position when the carriage is in the second orientation. A roll sensor senses the amount of absorbent web material remaining on the roll in the primary position. A feed mechanism dispenses absorbent web material from at least one of the rolls. A transfer mechanism feeds absorbent web material from the roll in the secondary position into the feed mechanism when the absorbent web material on the roll in the primary position is nearly depleted.

  • Patent number: 7168602
    Abstract: A dispenser having a transfer mechanism for transferring between a first source and a second source of sheet material, and a method for transferring between the first source and the second source. Dispensing is transferred from a first source to a second source upon an absence of sheet material from the first source. The transfer mechanism includes a transfer roller with a slot to receive a free end of sheet material from the second source. The transfer roller also includes a plurality of raised portions, the raised portions are free to rotate through a dispensing roller when there is an absence of sheet material from the first source. This rotation introduces the free end of sheet material from the second source to the dispensing roller, and allows dispensing from the second source. Afterwards, the transfer roller is set to receive sheet material from a new source of sheet material.

  • Publication number: 20060289331
    Abstract: Disclosed is a positioning and retaining assembly for securing an appliance in a carton that comprises a top cap and bottom pad. The top cap and bottom pad each includes a board and a plurality of clips secured to the board. The clips are arranged to engage the appliance at spaced apart locations around the periphery of the top and bottom of the appliance, respectively. In an alternative embodiment, one of the legs of each top clip has a ledge projecting outwardly from the top clip to engage the top of the appliance. In yet another embodiment, either the top cap or bottom pad can be replaced with a current roll-up design or molded foam, thereby only one of the top cap and bottom pad are used in the positioning and retaining assembly. The assembly is especially useful with water heaters.

  • Patent number: 7114677
    Abstract: A powered dispenser for dispensing individual sheet segments from a continuous roll of sheet material provided with spaced tear lines comprises a powered feed mechanism, a releasable, powered drive mechanism, a powered transfer mechanism, a pair of web sensing sensors, a capacitive sensing system providing automatic sensitivity adjustment, and control circuitry. A dual power supply system provides a mechanical lock-out functionality, and the control system is protected from electrostatic build-up on the surface of the feed roller. The web sensor, and an antenna plate of the capacitive sensing system, are provided on respective printed circuit boards mounted in overlying relation. Utilizing signals received from the pair of web sensors and the capacitive sensing system, the control circuitry senses the presence of a user to activate the powered drive mechanism, and prevents further dispensing of the sheet material until a previously dispensed segment is separated from the roll.

  • Patent number: 7063770
    Abstract: A hybrid method for processing papermaking fibers to remove high density stickies typically includes utilizing a multistage array of forward cleaners coupled with a flotation cell which increases overall efficiency of the system. In a preferred embodiment, a first rejects aqueous stream from a first stage bank of centrifugal cleaners is treated in a flotation cell before being fed to a second stage bank of centrifugal cleaners. With the improved technique, the accepts from the first stage bank of centrifugal cleaners may be combined with the accepts from the second stage bank of centrifugal cleaners and fed forward to a thickening device, for example. The technique is also suitably employed for removing stickies from material which has already been screened with a fine screen.
