PURPOSE:To make simply a uniform seal only by fingering, by arranging a pair of heaters confronting each other on two arms supported by a hinge, applying a large current with low voltage to the pair of heaters to control the heating and making the heaters to contact directly a sheet to be fused without any intermediate. CONSTITUTION:Two arms 3 and 4 having a hinge 5 and supported by the hinge 5 are made to be opened and closed by one hand. Then, a pair of heaters 1 and 2 having nearly the same shape and characteristics is arranged on said arms 3 and 4 so that they confront each other. Then, a large current with low-voltage is applied to said heaters 1 and 2 to heat them and they are made to contact directly a hot-melt sheet 55 with said heater formed in an exposed state. In this way, it is possible to make a heat seal exactly and quickly by a simple finger operation. |
