Abstract
In a paper towel dispenser of the type in which a user grasps a piece of the towel web projecting from a dispenser to pull out a section, which is thereupon automatically severed from the web, the improvement of belting together an internal drum which is driven by the web to sever the web and a safety roller, located at the slot through which the web is dispensed, in such an arrangement that the web is guided by the belt in its transit from the internal drum to the safety roller at the slot.
Claims5
In an apparatus of known type for the simultaneous dispensing and cutting of rolled-up webs of materials, with at least one roll of material in use, of the type in which the roll of material in use, mounted for free rotation on a support, is depressed directly against a drum with anti-skidding surface, so that by mere manual pull on the web of material protruding out from a slot in the housing of the apparatus, a web the length of which is approximately equal to the diameter of the drum will be dispensed and cut automatically by means of a toothed cutting device associated with the drum and projecting out of the drum, so that, when the drum is driven rotatably by pulling the material, the cutting device penetrating the material which is thereby stretched on either side of said cutting device, and the actuated drum returned by associated means to its initial position on completion of the cutting step, and a fresh web of material then protruded out of said slot in the housing of the apparatus, said apparatus being characterized by the improvement;
- in that the apparatus has a toothed cutting blade made of two portions (7a1 and 7a2) and housed within the drum (3) and each portion slidable transversely to the length of the said web in a common support (7) mounted pivotally (8) in the drum (3) for driving the material (B7) and cooperating with camming means (4c) for the periodic projection of the cutting blade out of the drum for cutting the material, means for providing a spacing between adjacent ends of the two portions of said cutting blade, on the one hand, for the passage therethrough of a belt (39) for transmission of the rotational motion between the drum and a safety roller (38) positioned at the level of said slot for the passage of the dispensed web or webs of material, and to minimize, on the other hand, the width of the uncut portion of the cut-off line of the web which occurs because of the absence of a tooth at the location of said space.
