A reusable protective template is formed by multiple layers: a first body-contacting layer made of a textile fabric and having bactericidal properties (silver ions, claim 2) and water-repelling properties due to chitosan fibres; an intermediate layer with silicone or a polymeric gel, and a third layer made of a textile fabric with means of attachment to a garment.

A substrate assembly is mechanically deformed to form various products. In part, the substrate assembly may advance toward a bonder apparatus. The bonder apparatus rotates about a longitudinal axis and includes a plurality of manifolds. The plurality of manifolds allow for substrate assemblies including different process product pitches to be processed on a single bonder apparatus.

Methods of forming a laminate may include conveying a first substrate through a first nip, where a first source of vibration energy may be used to alter a portion of the first substrate in the first nip to create an altered area. The method may include conveying the first substrate with the altered area and a second substrate into a second nip and using a second source of vibration energy to join the first substrate to the second substrate in the second nip.

A method and apparatus for mechanically deforming a substrate assembly. The substrate assembly may advance toward a bonder apparatus. The bonder apparatus may rotate about an axis of rotation. The bonder apparatus may include a plurality of manifolds positioned about the axis of rotation. The substrate assembly may be advanced onto the bonder apparatus such that the substrate assembly is disposed on the plurality of manifolds. Fluid may be passed to the manifolds onto which the leading edge portion and the trailing edge portion of the substrate assembly are disposed. The manifolds may heat the fluid and the heated fluid may be released onto the trailing edge portion and the leading edge portion of the substrate assembly. The heated portion of the substrate assembly may then be bonded forming a seam.

A wearable disposable absorbent article includes a front panel, a back panel, and a crotch panel bridging and at least partially overlapping the front and back panels. A backsheet of the crotch panel has a laminate structure including a liquid barrier sheet and a nonwoven layer arranged on top of each other. The liquid barrier sheet extends over the entire length of the crotch panel and further over at least a portion of each of the front and back panels. The nonwoven layer extends at least over the entire length of the crotch panel but not over a length of more than 40 mm over each of the front and back panels. The width of the nonwoven layer is smaller than the width of the liquid barrier sheet.

A manufacturing device is provided, within a range in the rotation direction of the upper half of an anvil roll, in the order from the upstream side in the rotation direction of the anvil roll, with a first sheet feeding unit, a recess forming unit, a particulate material feeding device, and a second sheet feeding unit and further a welding unit provided on the downstream side of the second sheet feeding unit in the rotation direction. The anvil roll has a large number of concaves, projections provided in a portion among the concaves, so as to surround each of the concaves, and a unit to suck air in the concaves. For each concave, the projections are minute dot-shaped projections arranged only in one row at intervals in the direction surrounding the concave.

A manufacturing apparatus for manufacturing a composite sheet associated with an absorbent article, including: a producing device that produces a substrate sheet by fixing a stretchable sheet to at least low-extensible sheet, the stretchable sheet continuing along a transporting direction, the stretchable sheet being in an extended state in which the stretchable sheet is extended in the transporting direction, the producing is performed while the producing device is transporting the stretchable sheet; a reference-section forming apparatus that forms a physical reference section on the substrate sheet, the substrate sheet being in a first extended state and being transported; a contraction apparatus in which the substrate sheet that has the reference section formed on it contracts until the substrate sheet becomes in a second extended state whose extension ratio is smaller than an extension ratio of the first extended state; and a processing apparatus that performs the certain process to the substrate sheet, the substrate sheet having contracted and being in the second extended state. The contraction apparatus includes: a transport path in which the substrate sheet is transported; a sensor that detects the reference section after the contraction in the contraction apparatus and that outputs a detection signal; and an alteration device that alters a transportation state of the substrate sheet in the transport path so that a position in the substrate sheet for the certain process is located close to a target position for the certain process, the alteration being performed according to the detection signal of the sensor.

The present invention provides a method of manufacturing an wearing article including: a front waist part which includes a left-front end and a right-front end; and a rear waist part which includes a left-rear end and a right-rear end forming, together with the left-front end and a right-front end, a left-side sealing portion and a right-side sealing portion. In the method, the left-side sealing portion in a layered state in which a fiber-supplemented sheet formed from a nonwoven fabric is layered on an elastic fiber sheet is formed in at least a portion of the article, the right-side sealing portion in the layered state is formed in at least a portion of the article, and, in at least a portion of the elastic fiber sheet, the fiber-supplemented sheet is not layered such that airflow is allowed to pass through the elastic fiber sheet.
