Device and method for manufacturing bag with chuck tape

A manufacturing device that manufactures a reclosable-tape-having bag, the reclosable-tape-having bag including a first base material and a second base material, the first base material and the second base material being superposed together so that a periphery of the base materials are joined to form a bag body, a reclosable tape having a male fastener and a female fastener that are engageable with each other, the reclosable tape being mounted on an inner surface of the first base material of the bag body, an open tape being adapted to rip and open the bag body and provided between a mounting base of either the male fastener or the female fastener and the first base material of the bag body,

• the manufacturing device comprising:
• a notching instrument that notches the bag body, wherein
• the notching instrument includes:
• a whole-notching instrument that punches the first base material, the second base material, the open tape and the mounting base to form a tab on an opening trigger provided on a side seal of the bag body;
• and a half-notching instrument that forms an incision on the second base material and a portion of the mounting base corresponding to a position of the open tape, and
• the whole-notching instrument and the half-notching instrument are adjacently provided such that the tab formed by the whole-notching instrument is substantially continuously connected with the incision formed by the half-notching instrument.
