A heat-sealing apparatus includes a casing, a pair of lower and upper binding members for vertically binding a portion of a heat-fusible wrapper therebetween, a heater attached to a binding face of the lower binding member which is in turn fixed to the casing. The heater is operable to heat-fuse the portion of the wrapper. The apparatus further includes a switching mechanism for switching over the upper binding member between a binding position where the upper binding member is pressed against the binding face of the lower binding member and a releasing position where the upper binding member is retracted in an upper-rear direction away from the binding face of the lower binding member. The upper binding member is a heat-resistant elastic pressing roller rotatable about an axis extending along a length of the heater. |
