    摘要: A heating blanket cover is constructed from a lower sheet, which may include a first material layer laminated to a second material layer, and an upper sheet bonded to the lower sheet along a longitudinally extending bonding site, wherein the upper sheet extends laterally from the bonding site over the lower sheet to a free edge. The bonding site may be formed by heat sealing the upper sheet to the lower sheet. A gap between the upper sheet and the lower sheet forms an enclosure to hold the heating blanket; the enclosure is accessible by lifting the free edge of the upper sheet away from the lower sheet. A series of covers may be formed, for example by a web-manufacturing process, by bringing together at least two lengths of materials, bonding the lengths together and assembling the lengths on a roll for dispensing of individual covers from the series.
