A dispenser assembly designed to tangentially dispense a sheet from a roll of sheet material including sheet material formed from two webs, each web having lines of weakness positioned transversely across the web which allows the web to be separated into a plurality of sheets, the lines of weakness of one web being offset from those of the other web. The dispenser assembly includes (1) a base arranged to hold the roll of sheet material and to couple the dispenser assembly with an environment structure; (2) a first roller and a counter roller between which the sheet material is movable towards a dispensing outlet; and (3) a cradle arranged to support the roll of sheet material and to unwind the sheet material towards the first roller whatever a consumption level of the roll of sheet material. The first roller and the counter roller are positioned relatively to each other spaced according to a fixed nip therebetween to generate a braking force on the sheet material sufficient to break the line of weakness of the web at the dispensing outlet or downstream the dispensing outlet.

The present disclosure provides improved tape dispensers that include a case featuring a pair of opposing main plates each coupled to two circumferential wall plates. The main plates, and corresponding circumferential wall plates, are rotatable relative to one another to expose a support structure for a tape roll. A cutting blade may be provided on one of the circumferential wall plates and may include a substantially arc shaped support surface.

An improved towel dispenser includes a rotatable driveshaft mounted in a one-way clutch bearing fitted with a pinion which engages a vertically oriented press bar assembly including at its lower portion a rack which engages the pinion to advance paper towel through a dispensing nip upon pivotable motion of the press bar assembly. A dispensing chute located below the dispensing nip includes a lower shelf configured to direct web forwardly toward the front portion of a dispenser. The gear rack is preferably an internal gear rack integrally formed with a unitary press bar assembly member. The dispensing chute is configured such that an angle between a cutting-blade and the outer lip of the shelf makes an angle with a vertical of at least about 25.

A container-unroller for film, aluminum sheet or similar material wrapped around a roll where the container-unroller has a tubular body for the accommodation of a roll to be contained and a means for control of one-way rotation of said roll. A means for making a hot electric cut and a means for making a tear cut are positioned on the same device where the means for making a tear cut are a metallic saw-toothed bar, connected to electric current. means for making a hot electric cut.
