摘要:
A dispenser of a web wound into a roll includes a support rod and at least one substantially vertical wall, the support rod being inclined relative to a horizontal direction. The roll includes a central borehole which allows mounting of the roll on the support rod of the dispenser. The roll rests by one transverse end surface of the roll against the at least one substantially vertical wall of the dispenser.

A dispenser for sheets of fibrous material, such as a non-woven or cellulose wadding of a specific surface weight between 15 and 90 g/m.sup.2 per ply, a strip of the fibrous material wound into a roll and pre-perforated so as to provide a sequence of sheets linked to one another by rows of perforation bridges. The dispenser is fitted with a feed cone. The material is dispensed by the cone through a smaller diameter apex. The proportion of perforation bridges is selected to be no more than 30% above that constituting the machining limit of the fibrous material and in that the diameter of the apex of the cone is between a minimum value corresponding to a force of removal just exceeding the force of rupture of the material and a maximum value corresponding to an effectiveness equal to or larger than 90%, in particular equal to or larger than 95%.

The invention proposes a dispenser of paper, or other equivalent product, including a housing storing the product in the form of folded sheets to be dispensed through a dispensing opening. The paper is contained in a detachable cartridge compatible with the paper dimensions and assembled to the dispenser inside the housing. The cartridge includes an end wall situated opposite an opening of the housing wherein is located a dispensing slot of which the shape matches the paper sheets to be dispensed. The cartridge includes walls which guide the stack of folded sheets.
摘要:
A process for treating natural cellulose fibers, in particular cotton fibers, comprising the stages of depositing the fibers on a continuously moving wire to form a lap evincing a specific surface weight of 100 to 800 g/m.sup.2, impregnation with a treating solution, treatment, and rinsing using an aqueous liquid, characterized in that rinsing is carried out by applying the liquid in the form of jets directed at one side of the lap perpendicularly to its direction of advance at an energy between 2 and 60 kwh/ton of treated product. The rinsing station (100) comprises at least one needle injector (105, 115) situated across the lap and applying highly pressurized water jets to its surface. The liquid is sucked in through a transverse slot communicating with a suction box (110, 125).

The invention proposes a dispenser for a web wound into a coreless roll, the roll (11) being mounted on an irrotational, substantially cylindrical support spindle (14), the web in this dispenser being dispensed by rotationally unwinding the roll (11) around the axis (A1) of the support spindle (14), characterized in that the support spindle (14) includes means (46, 48, 50, 52) axially locking the roll (11) and in that the spindle (14) bears means (36, 50, 52) for decelerating the roll (11) being unwound.
摘要:
The general application of the invention is a finishing process for an air-laid nonwoven web composed of short cellulosic fibers, bound by a thermoplastic binder and having a less than perfect homogeneous fiber distribution. In the invention, the process includes deforming under hot stress the web between an undeforming hard engraved cylinder and a slave cylinder having a hardness between about 60 and 90 degrees shore hardness D. The slave cylinder is resilient and deformable at the pressure applied to it by the engraved cylinder. In particular, the invention applies to the manufacture of webs and of disposable, decorative napkins.

摘要:
A skin-cleansing article that is activated by moistening with water, followed by a mechanical action so as to obtain a cleansing foam, includes a fibrous substrate and a cleansing composition. The substrate is a pad based on water-jet-entangled cotton fibres with a basis weight of between 100 and 300 g/m2, and the cleansing composition includes at least one surfactant and a humectant such as glycerol, the amount of water on the substrate being less than 25% by weight of the article, and the article having from 0.1 to 1.2 gram of active material of the composition per gram of the substrate.

摘要:
The invention concerns a method for making a non-woven from unbleached cotton or other natural ligno-cellulose fibers comprising a surface layer of substances rendering the fiber hydrophobic and comprising the following stages:formation of a sheet of unbound fibers on a water-permeable cloth,tangling the sheet fibers by means of a plurality of water jets issuing from arrays of injectors located transversely to the direction of advance of the support, the method being characterized in that the total energy imparted to the sheet by the set of jets is at least equal to a minimum threshold corresponding to the value at which said sheet becomes hydrophilic.The invention also concerns a hydrophilic non-woven made by hydraulic binding from unbleached cotton or other natural, ligno-cellulose fibers such as flax, hemp or ramie and free of chemical treatment.
