A47C 21/00 - Attachments for beds, e.g. sheet holders or bed-cover holders Ventilating, cooling or heating means in connection with bedsteads or mattresses
Devices and methods for fusing materials using a heating element, where the overall mass to be sealed varies along the length of the seal. According to the invention, the heating element has a different profile in different areas. According to some aspects, the thickness and/or cross section of the heating element is different in different areas so that when a current is passed through the heating element, each area heats to a different degree. In some aspects, the heating element is shaped to conform to the shape of the parts to be fused together. The transition between areas of different thickness or cross-sectional area, or between areas of different shape may be sharply defined. This abrupt transition may be created by machining the heating element to a finished shape rather than bending flat stock to shape.
An article of manufacture that has at least three layers of heat sealable material. There is at least one first heat seal between at least two of the layers in a first area effected at a first temperature. There is also at least one second heat seal between at least two more layers, where at least one of these two layers is distinct from the at least two layers joined by the first heat seal, in a second area effected at a second temperature, where the second temperature is different than the first temperature, thereby allowing for heat sealing of discrete areas of the article in discrete steps.

An expandable structure is manufactured using sheets of thermoplastic material sealed together. The expandable structure has a concertina pattern on its sides that allows the structure to expand and collapse like an accordion. The concertina pattern is cut into the sheets of material rather than being folded into the material to speed up the manufacturing process.
