摘要

An electric heat-sealing heater has a flat heating sheet member having embedded therein a resistance heating element. The sheet member is supported on a rigid guide with an elastic rubber sheet interposed between the guide and the sheet member. A flexible copper heat accumulating block having a plurality of slits alternately extending in a direction transverse of the heater is positioned on the side of the heating sheet member opposite to the rubber sheet and is retained in place by a holder having a pair of arms and mounted on the guide. The flexible block is adapted to be pressed against the material to be heat-sealed and accommodates any uneven surfaces on the parts being sealed.
