    Abstract: A dryer section employs top-felted and bottom-felted dryer sections, each comprised of a single steam-heated drying cylinder with a diameter of about 12 feet. The web is transferred between drying cylinders by a two vacuum roll transfer without an open draw. The dryer fabric wrap on the large dryer cylinders is over 270 degrees resulting in large drying capability per dryer roll. Because each large dryer is followed by another large dryer roll which dries the opposite side of the web, uniformity of drying is maintained. Each dryer cylinder may have its own dryer fabric stretcher and guides. Alternatively, individual dryer fabrics service multiple top-felted dryers and bottom-felted dryers, respectively. The web is constrained approximately 96 percent of the time as it passes through the dryer section. The dryer section can achieve 2.9 inches of dryer surface in the machine direction for every inch of dryer section.

    Abstract: A bag breaking apparatus has an apron feeder type conveyor (21) with an apron constructed of overlapping pans (24). Thin upstanding triangular teeth (51) are mounted to each pan parallel to the direction of motion of the conveyor. Bags of trash (46) are supplied to the conveyor and progress to an outfeed end (52). A roll (54) is positioned over the conveyor near the outfeed end. The roll is driven about the axis (56) of the roll. Triangular teeth (60) mounted to the roll interdigitate with the teeth on the conveyor thus rending the bags which pass between the roll and the conveyor. The roll can be raised and lowered to accommodate bags of different sizes and is pivotable to swing upwardly when faced with oversized or excessive amounts of trash and thereby allow the material causing the jam to pass under the roll and off the outfeed end of the conveyor.

    Abstract: Two water jets cut a paper web (26) as it is led over a winder drive roll (36). The water jets are angled with respect to the cut so the water used in the cutting action is entirely directed onto the portion of the web which is severed. An adhesive material, for example an automatically applied tape (24), is introduced between the upper surface of the web (26) and a spool (28) for forming a new reel (32) of paper. The use of an adhesive causes the paper leader to engage with the spool (28), thus assuring a tight, uniform and consistent initiation of the web wrapped onto the new spool (28). An automatic tape applicator (22), similar to that used for taping cardboard boxes, may be used to insert a double-sided adhesive tape (24) onto the web (26) or into the nip (40) formed between the spool (28) and the winder drum (36).

    Abstract: A tissue dryer has a dryer roll which is externally heated by induction to raise the roll surface temperature to between 300-700 DEG F while allowing internal hydraulic crown support of the roll. The hydraulic support of the roll exerts pressures of between 1 000-10 000 pounds per linear inch. The drying performance of the dryer is enhanced by providing a prewarp of the web onto the hot roll just before the pressing nip. After the web transits the nip it is removed by a doctor blade which crepes the web. The web is fully restrained during the majority of the drying process thus requiring no adhesive sprays.
