Abstract: Apparatus and procedures for continuously forming rosette shaped tampons from aggregate containing tubular sacks or overwraps having withdrawal strings at one end and assembling the tampons in inserters, the apparatus comprising rotary transfer mechanism for engaging the withdrawal strings of the sacks and sequentially delivering them to a rotary assembly turret having a multiplicity of assembling stations mounted around its periphery. Each inserter comprises inner and outer parts, and feeding means are provided to individually feed and position an inner inserter and an outer inserter in holders at each assembly station. Each station has a reciprocating string engaging rod which acts to remove a sack by its string from the transfer mechanism and positions the sack to be drawn upwardly by vacuum into an overlying annular inversion chamber wherein the sack is inverted into rosette shape by the action of a pressure-vacuum reciprocating inversion rod.

Abstract: A device for applying glue to chips, fibers or the like particles of cellulose containing substances, such as wood, bagasse, or the like, with an at least approximately cylindrical chamber in which the material to which the glue is to be applied passes through an inlet chute, an inlet zone, a gluing zone following the latter, a post-mixing zone, and an outlet in the form of a ring of material rotating along the cylindrical wall of the chamber, and in which on a shaft extending through the chamber, in the inlet zone there are arranged conveying tools which are provided with a vane or paddle-shaped working surface. Tools are arranged in the gluing zone and post-mixing zone for applying glue to and mixing the material.

Abstract: In a deep pile fabric knitting machine which includes carding wheels from which fibers are transferred to rotary doffers and from which the fibers are selectively taken by knitting needles traveling with a rotary cylinder, but with at least some untaken fibers remaining on the doffers, remaining fibers are scavenged from the doffers, substantially uniformly dispersed and returned for recycling in the same carding paths from which the fibers were originally transferred to the doffers. Returned fibers may be applied directly to the perimeters of the carding wheels, or to sliver leading to the carding wheels. Scavenging may be effected by high speed scavenger rolls and return of the fibers effected pneumatically with mechanical dispersion. Loose fibers are blown from the knitting needles and recycled in the same system with the fibers scavenged from the doffers.

Abstract: A method of pneumatically traversing a linear fibrous element during its packaging in a rotated perforated canister as air is withdrawn from the canister through its sidewalls and bottom wall; the air moves downwardly through the package during package formation to prevent freedom of movement to the element in the package and air moves generally horizontally as it is withdrawn uniformly from all sides of the canister through its perforated sidewalls to reduce air turbulence in the canister to promote ordered collection of the fibrous element.

Abstract: The present invention relates to papermaking and particularly to a method of producing a fibrous web of uniform thickness and variable width which comprises feeding fibres from a supply zone which is in a fixed position and has a first lateral dimension into an expansion zone, permitting said fed fibres to fall through said expansion zone while moving laterally outwardly to form downwardly progressing zones of progressively decreasing fibre density, establishing a suction zone beneath said expansion zone said suction zone having a second lateral dimension which is variable and greater than said first lateral dimension and reducing the pressure in said suction zone to below the pressure in said expansion zone by an amount sufficient to form a web of fibres between said expansion and suction zones but insufficient to prevent said laterally outward movement of said fed fibres and forming a web of fibres between said expansion and suction zones which extends over the whole width of said second lateral dimension a

Abstract: In the apparatus of the invention a slot nozzle is arranged on an outlet of a pipe for supplying an air-fibre dispersion stream into a chamber with said nozzle disposed therein so that the slot of the nozzle is perpendicular to chamber side walls. A body with a curvilinear cambered plane is disposed in the chamber and is essentially a cylinder with a generatrix length of no less than the nozzle slot length. Said cylinder has a diameter no less than 1.2 times the nozzle slot width and is spaced under said nozzle at 0.3 to 1.0 cylinder diameter. In addition, a spacial lattice, spanning over a chamber cross-section for smoothing the air-fibre stream, is placed under the cylinder 2 to 6 diameters of the latter down stream from the nozzle and the cylinder.

Abstract: A calender roller apparatus is provided for use with sliver coilers and the like wherein a sliver is passed for delivery between surface engaging coiler rollers rotatably carried on a pair of parallel roller assemblies. One of the roller assemblies is fixed to a base platform and the other roller assembly is pivotably carried by the base platform at a point which is above the center line of the pivoted roller assembly providing a downward biasing force to the pivoted roller against the surface of the fixed roller, so that the sliver will be suitably compressed therebetween eliminating the need for a positive lock-down means which is normally found on pivotable calender rollers.

Abstract: Fibers are air laid on a twin-wire machine to form a composite pad. A pair of endless foraminous carriers are passed through a forming chamber where fibers suspended in air are directed between the carriers. A layer of fibers is built up on each of the carriers by applying pressure differential across the carriers in the chamber to force air from the suspension through the carriers. In one form of the invention the air is directed through the respective carriers in different patterns to form a respective fiber layers of different cross section. The carriers converge within the chamber in their direction of motion to join the facing surfaces of the respective layers to form a composite pad of non-uniform cross section. According to one aspect of the invention, excess fibers are removed from the facing surfaces just prior to their being joined.
