Feed assist apparatus for a flexible sheet material spreader
A feed assist apparatus for a flexible sheet material spreader, comprising a first arm attached at a first end to one side of the material spreader, a second arm attached at a first end to another side of the material spreader, and a material retainer attached at a second end of each of the first and second arms, the material retainer having a first configuration for feeding flexible sheet material there-through and a second configuration for retaining flexible sheet material. The first arm and the second arm are moveable together from a first position adjacent a flexible material supply and a second position adjacent entry to the material spreader, and the material retainer is in the second configuration when the moveable arms are in the first position, and the material retainer is in the first configuration when the moveable arms are in the second position.
Torque and skew reduction in tubular knitted fabric
The present invention includes aligning ring guides disposed at opposite angles to each other to force the tubular knitted fabric to turn in a spiral direction allowing the wales or rows of stitches to rest at an angle with respect to the edge of the tube of fabric. This is the normal or resting state and position of the wales in a wash-tested sample or laundered garment. This is accomplished by a pair of add-ons for torque and skew reduction in a tubular knitted fabric, which includes a crossbeam and a pair of angled ring guide assemblies that depend from the crossbeam. Each angled ring guide assembly has a mount with a fixed portion and a movable portion, and further has a guide ring, with each angled ring guide assembly being disposed on the movable portion. The fixed portion contains a crescent-shaped slot, with the movable portion containing a peg that rides in the slot.
Method for making a shaped nonwoven
A method for making nonwoven fabric. The nonwoven fabric can include three-dimensional features that define a microzone comprising a first region and a second region. The first and second regions can have a difference in values for an intensive property. The nonwoven further has a plurality of apertures, wherein at least a portion of the aperture abuts at least one of the first region and the second region of the microzone.
Nonwoven fabric sheet and method for making the same
The invention relates to a patterned spunbonded nonwoven fabric sheet comprising a plurality of spunbonded crimped fibers bonded together at a plurality of bonding points, wherein all fibers of the patterned spunbonded nonwoven fabric sheet are spunbonded crimped fibers and wherein the configuration of the fibers within the sheet is inhomogeneous and varies according to a preferably regular pattern. The invention further relates to a method for forming such patterned spunbonded nonwoven fabric sheet from a flat spunbonded nonwoven fabric sheet starting material. Still further, the invention relates to such flat spunbonded nonwoven fabric sheet starting material.

SHEET MANUFACTURING METHOD AND PROCESSING DEVICE
A sheet manufacturing method includes a conveying step of conveying a base material sheet; and a processing step of rotating a pair of processing rolls to sandwich a conveyance path on which the base material sheet is conveyed, wherein irregular portions along respective outer peripheral faces of the processing rolls engage with each other with a clearance to stretch the base material sheet when the base material sheet passes between the processing rolls. In the conveying step, the base material sheet is conveyed such that the base material sheet contacts along the outer peripheral face of one of the processing rolls immediately prior to passing between the processing rolls; and the tension in the conveyance direction applied to the base material sheet immediately prior to reaching the outer peripheral face of the one of the processing rolls is less than 10% of a breaking load of the base material sheet.

Roller for guiding and/or width stretching of a running material web
A roller (1) is used for guiding and/or width stretching of a running material web (2). The roller (1) has a supporting body (3), on the outside of which receptacles (4) for axially displaceably held battens (5) are provided. These grasp the material web (2). In order to improve the functionality of this roller (1), at least one undercut groove (6) is formed on the supporting body (3) between at least two of the battens (5). This undercut groove (6) can receive at least one functional component (7).
STRETCH LAYERED SHEET, DISPOSABLE WEARING ARTICLE, AND METHOD AND DEVICE FOR MANUFACTURING STRETCH LAYERED SHEET
The present layered stretchable sheet includes: a plurality of attachment portions at which a pair of non-woven fabrics and a film are thermally bonded together, wherein each one of the attachment portions includes at least one thermal bonding area where the pair of non-woven fabrics and the film are thermally bonded together; at least one boundary line that defines the thermal bonding area; a first vent that is defined by a first opening of the film appearing in a stretched state of the film along the boundary line and that exerts air permeability; and a second vent that is defined by a second opening where a part of the film is absent, the second opening being adjacent to the thermal bonding area and being delimited by the boundary line, wherein the second vent exerts air permeability both in the stretched state and in a non-stretched state.
