The invention provides a sheet material dispenser and more particularly a dispenser for storing and dispensing a compact stack of folded tissue products. The compact stack of folded tissues may be secured by the tension of a pair of opposed side panels having a generally elliptical shape. The elliptically shaped side panels result in a rigid, resilient frame-work such that the dispenser has sufficient resiliency to maintain its shape even after a portion of the folded tissue products have been dispensed.

A film-packaged product with excellent withdrawability of sheets of sanitary tissue paper has a bundle of sanitary tissue paper packaged with a flexible resin film, and includes a dispenser-port-forming region formed by disposing an easy-tear line in a loop in the top face, the region has a narrowed section extending widthwise in the middle of the depth direction, flaring sections each gradually flaring with increasing distance from the narrowed section outward widthwise, and curved convex sections each bulging convexly outward widthwise, and the width of the region is 70% or more the width of the top face, a maximum depth of the region is 10 to 40% the depth of the top face, the width of the narrowed section is 50 to 70% the length of the top face, and the depth of the narrowed section is 0.5 to 10% the depth of the top face.

An interfolding machine produces interfolded sheets according to an interfolding configuration and, starting from a web of paper provides a feeding section, which applies a tension on the web and moves the same along a feeding direction feeding the same to a cutting section, in which the web of paper is cut into a series of sheets at a cutting point between a cutting roller and a counter-cutting element. Downstream of the cutting section, a folding section includes a first and a second folding rollers counter-rotating with respect to each other. The first and second folding rollers rotate about respective rotation axes with a first peripheral velocity vP, and fold, at a folding zone, a plurality of sheets in a plurality of panels and form the stack of interfolded sheets. The cutting roller alternately distributes the aforementioned sheets between a transfer roller and the first folding roller.

The invention provides a fiber product folding and stacking system comprising at least one folding wheel, a plurality of suction channels, a plurality of valves and a plurality of passages. The folding wheel includes a plurality of protruding wheels and a plurality of recessing wheels. The protruding wheels and the recessing wheels are adjacent to each other, and suction channels are arranged within the protruding wheels. The passages are disposed in the folding wheel and are fluidly connected to the suction channel. The valves are disposed within the recessing wheels of the folding wheel, and include a connecting opening, a valve channel and a valve opening. When the folding wheel rotates, portion of the suction channels will be fluidly connected to the valve channel through the passage and the valve opening to generate a negative pressure thereon for absorbing the fiber product.

An apparatus forms stacks of interfolded sheets. First and second folding rolls receive the plurality of sheets, move the plurality of sheets through the nip, and fold the plurality of sheets into a stack of interfolded sheets downstream of the nip. A packing finger is associated with each folding roll, and the respective packing fingers move between a retracted position and an extended position relative to the corresponding folding roll with alternate movement relative to each other between the retracted position and the extended position to engage the plurality of sheets and form the stack of interfolded sheets. A fluid delivery system delivers fluid to a sheet in the plurality of sheets at or after the folding rolls.
