摘要： A product metering napkin dispenser includes a housing defining a storage magazine for receiving a stack of folded napkins and a metering member that penetrates the stack in order to segregate a predetermined number of napkins from the remainder of the stack for dispensing. Preferred embodiments include gravity feed napkin dispensers. In various embodiments the metering member may include: a pivoting plate cooperating with a hinged trap door support surface; a rotating semicircular disk co-rotating with a support disk; or a reciprocating jaw assembly urging napkins through an aperture.

摘要： A web transfer mechanism provides, in a flexible sheet material dispenser, automatic transfer of web feed from a working roll to a reserve roll, using a sensor plate operatively coupled with a transfer arm. A sensor plate providing a pivotable stub roll receptacle cover senses the absence of web from the stub roll at a pre-feed portion between the stub roll and a feed roll nip to activate a transfer of feed to the web of a reserve roll. The transfer is initiated by a transfer arm that advances the reserve web into the proximity of the feed roller nip. The pre-feed sensing position of the sensor plate makes the web transfer mechanism well suited to adaptation to known dispenser types including a web cutting knife which emerges from within the feed roller. At the same time, double feed of web material at the time of transfer is minimized. In a second aspect, a movable front shield opens automatically upon opening of the outer dispenser cover, presenting an opening for pre-transfer placement and retention of a leading edge of web material from the reserve roll. Upon closure of the dispenser cover, the front shield returns to a closed position placing the transfer arm in a pre-transfer set position.

摘要： A process for making absorbent sheet includes: (a) depositing an aqueous furnish of cellulosic fiber on a forming fabric; (b) dewatering the wet web to a consistency of from about 15 to about 40 percent; (c) transferring the dewatered web from the forming fabric to another fabric traveling at a speed of from about 10 to about 80 percent slower than the forming fabric; (d) wet-shaping the web on an impression fabric whereby the web is macroscopically rearranged to conform to the surface of the impression fabric; and (e) impingement air drying the web. The process is particularly suitable for making high bulk products form difficult to process furnishes such as recycle furnishes and for making high basis weight products without compressive dewatering with a papermaking felt.

摘要： A process for producing high bulk cellulosic fiber exhibiting a durable elevated curl index includes: (a) concurrently heat treating and convolving cellulosic fiber pulp at elevated temperature and pressure at high consistency under conditions selected so as to preclude substantial fibrillation and attendant paper strength and fiber bonding development; and (b) recovering the pulp wherein the length weighted curl index of the treated fiber is at least about 20% higher than the length weighted curl index of the fiber prior to the heat treatment and convolving thereof. The curl imparted to the fiber persists upon treatment for 30 minutes in a laboratory disintegrator at 3000 rpm at 1% consistency at a temperature of 125°F. Moreover, the curl may be imparted to the fiber in a disk refiner at very short residence times, on the order of several seconds or less. In general, the process is carried out in the presence of saturated steam at a pressure of from about 5 to about 150 psig.

摘要： Distributeur (10, 200) pour découper et acheminer une bande (W) de matériau en feuille souple, dans lequel un rouleau alimentateur (30, 212) porte une lame coupe bande (40, 226) et un ressort (104, 290) relié à une manivelle excentrique (102, 288) fixés sur le rouleau alimentateur (30, 212). Tandis que le déplacement initial de la bande (W) par l'intermédiaire du mécanisme et de l'actionnement de la lame (40, 226) pour effectuer la séparation partielle du matériau en bande (W), est produit par la traction de l'utilisateur sur ladite bande, cette traction exerce également une charge sur le ressort (104, 290) qui, lorsque la charge est supprimée, fait sortir la bande coupée du distributeur (10, 200). Le ressort (104, 290) conçu pour arrêter graduellement la rotation du rouleau alimentateur (30, 212) et pour libérer l'énergie emmagasinée exerce, par traction continue de la bande (W), une contrainte graduellement croissante sur les segments non coupés de ladite bande jusqu'à leur rupture, après quoi les segments non coupés de matériau en bande (W) sont efficacement sectionnés et l'extrémité avant (WE) de la bande suivante est automatiquement positionnée à l'endroit où elle peut être aisément saisie par un autre utilisateur.

摘要： A stop mechanism for a feed roller (4) associated with a cutter in a dispenser for flexible rolled web material (W) has a stop lever (15) which provides a substantial mechanical advantage. The increased mechanical advantage permits the vacuum cups (13,14) of a vacuum cup timer to be effortlessly and reliably set. The stop lever (15) has a long actuating arm (12) which pivots about a pivot point (11). A long engagement arm (18) of the lever (15) has a camming surface (10) which is engaged by a lug (9) carried by a feed wheel (8) rotatable with the feed roller (4) in order to bring the actuating arm (12) into a position in which the vacuum cup timer is set.

摘要： A process of making a deicing or dust control agent with reduced corrosivity comprises mixing spent sulfite liquor and chloride salt of an alkali metal or alkaline earth metal proportionally so that the ratio of lignosulfonate solids of the spent sulfite liquor to metal chloride salt is from about 1:25 to about 15:1 and the pH of the mixture is from about 4.5 to about 8.5. The sulfite liquor: chloride salt product can be spread onto road surfaces in dried form, sprayed on as single or multiple solutions, and/or mixed with a non-slipping agent or the like.

摘要： A dispenser and dispensing method for flexible web material that is wound into a roll on a readily deformable hollow core (C) has a housing carrying opposed parallel guide tracks (22-24) to guidingly receive roll core supports (E,F) projecting from the roll ends and a spring biased lever (40) pivoted on such housing, the lever (40) applying an axial force to the hollow core (C) at one roll end and being maintained in a roll retaining condition by the presence, in a roll dispensing position, of a hollow roll core that is held against downward displacement from such position. An axial force (FR) is applied against the other end of the hollow core. The lever (40) serves to retain a reserve roll (R) in a reserve roll position remote from the roll dispensing position with the lever (40) being released from such retaining condition when the web material is exhausted and the hollow core (C) is deformed downwardly, assisted by the axial forces (FR) applied to the hollow core ends, to enable removal of this core (C) from the roll dispensing position whereupon such reserve roll (R) moves to the dispensing position.

摘要： A dispenser for rolls of flexible sheet material has a feed roller (30) with a pair of pinch rollers (74,76) spaced around the feed roller periphery to guide a web (W) of the material from a supply roll (R) to the dispenser exit (20). A cutting blade (40) is slidably mounted within the feed roller to move in a path parallel to and offset from a radius of the feed roller with cam followers (62) movable with the blade and extending beyond the ends of the feed roller disposed to reciprocate along this radius. Stationary cams are mounted adjacent the ends of the feed roller engaged with the cam followers, respectively, to positively project the blade cutting edge beyond the feed roller periphery to cut the web and retract such edge as the feed roller is rotated by drawing on the web at the dispenser exit.
