A method of manufacturing a face mask comprises coupling at least one tensioned elastic structure to at least one web material to form a continuous elastic strap, advancing the continuous elastic strap in a machine direction, coupling the continuous elastic strap to a multi-layer mask web traveling in the machine direction to form a continuous face mask composite structure, and cutting the continuous face mask composite structure to define a plurality of discrete face masks. The multi-layer mask web comprises an inner web layer, an outer web layer, and a filter layer positioned therebetween.

Disclosed is a guiding apparatus for use with a machine to facilitate performing an action along a self-guided path on a substrate. The guiding apparatus may include a support member configured to be attached to at least a portion of the machine. Further, the guiding apparatus may include one or more of lighting units, optical sensors, controllers, and user interface components, mounted on the support member, configured to identify an object, obtain position of the object on a substrate and perform an action along a self-guided path in association with that object on the substrate.

Proposed is lower rollers of a hot air welder, and more particularly, to a lower roller structure of a hot air welder, which includes a first lower roller unit installed on a worktable to be pivoted vertically and a second lower roller unit installed on a main body to be slidably moved in front and rear, such that a welding operation of flat fabric and a welding operation of a cylindrical shape can be performed in a single hot air welder through alternate use of the first and second lower roller units.

A wet sportswear takeoff helping device for the upper sportswear that is worn extremely tight to the wearer's skin; where the takeoff helping device includes one or more guides for guiding the corresponding drawstrings and a handgrip used for activation. The guides are made on the back part of the upper sportswear, each guide begins close to the hemline and propagates to the upper part of the sportswear in a continuous way, or having one or more interruptions formed along the guide. Pulling of the handgrip by the wearer's hand causes lifting of the sportswear's hemline towards the wearer's neck to facilitate removal. The invention is applicable to an ordinary T-shirt takeoff device for helping elderly or disabled people to take off the upper garment.

A performance monitoring system includes an athletic band or other article of apparel worn by a user, with a pocket supported by the article and defining a cavity, where the pocket has a sensor opening extending through an inner wall of the pocket and an access opening providing access to the cavity. The system also includes an electronic module received in the cavity such that the module can be inserted and removed from the cavity through the access opening. The module has a projection on an underside of the electronic module and a sensor mounted on the projection, where the projection extends through the sensor opening when the electronic module is received in the cavity and is configured to place the sensor in close proximity to skin of the user, such that the sensor is configured to sense a physiological parameter of the user.

A process of manufacturing a down product comprises at least one bonding pattern line for the compartment separation without forming sewing holes by printing and drying a heat-reactive adhesive on the inner surface of an inner fabric, an optional mesh material and/or an outer fabric in a predetermined pattern, laminating said inner fabric, optional mesh material and/or outer fabric, and then high-frequency heating them under pressing with a pressing pattern the same as the printing pattern to bond the inner fabric, optional mesh material and outer fabric. Accordingly, it is possible to manufacture a down product having a bonding pattern line composed of a bonding line with excellent adhesiveness and durability and an aesthetically excellent pattern line with good clearness and finishing quality as well as to achieve a mass production of down products by mechanization and automation.
