Matratze und Verfahren zur deren Herstellung

摘要

A pad (6) is arranged on the upper and lower sides of a spring unit (1) to provide a laminate structure. The laminate structure is covered with an outer cover body (7) comprising top and bottom layers (8, 9) covering the corresponding pads and a side layer (11) covering the laminate structure. A joining member (13) of heat-shrinkable synthetic resin have one end width portion joined to the inner surfaces of the whole marginal edge portions of the top and bottom layers (8, 9). The other end width portion of the joining member cover the corresponding outer marginal edge portions of the pads (6). The joining member (13), upon being heat shrunk, have their other end width portion brought into firm engagement with the spring unit (1) so that the pads (6) and outer cover body (7) are firmly held relative to the spring unit (1).
