The present invention provides an apparatus for producing and putting on gloves capable of producing gloves that fit an individual hand shape and also putting the glove on the hands, and a method for producing and putting on gloves. The apparatus [1] for producing and putting on gloves comprises welding and cutting means which welds and cuts a first elastic film and a second elastic film at a position on the outer side of a contour of a user's hand in a state in which the user's hand is sandwiched between the first elastic film and the second elastic film.

A structured fluoropolymer film including a plurality of structures having a height at least two times a thickness of a corresponding unstructured fluoropolymer film and at least a 20% increase in displacement induction period when compared to the corresponding unstructured fluoropolymer film when measured in a biaxial tensile curve at a temperature of about 125° C. In addition, the structured fluoropolymer film has a methane permeability of less than 500 μg*μm/cm.sup.2/min. The structured fluoropolymer film exhibits a higher resistance to strain and retain barrier properties during manufacture and/or use.

A downhole probe of a drilling rig has a probe sleeve for protecting the downhole probe. The probe sleeve may be made of a metal or a polymer such as polyphenylene sulfide. The probe sleeve may be heat-shrinkable to provide a tight fit between the downhole probe and the probe sleeve. The probe sleeve may include one or more protrusions shaped to engage a centralizer surrounding at least part of the downhole probe. The one or more protrusions may be arranged to prevent rotation of the centralizer relative to the probe sleeve. The probe sleeve may be made using a modified extrusion process and may include reinforcement to add strength to weld-lines along the length of the probe sleeve. The protrusions may also be used as reinforcement.

A multilayer composite is disclosed comprising a heat shrinkable polymer layer and a nanofiber layer. Methods of forming the composite and uses thereof are also described.

The heat-shrinkable film includes a block copolymer comprising a vinyl aromatic hydrocarbon-derived structural unit and a conjugated diene-derived structural unit as a main component.
