Abstract
A manufacturing device for manufacturing a reclosable-tape-having bag manufactures a reclosable-tape-having bag in which a reclosable tape is mounted on an inner surface of a bag body 10 while an open tape 23 for ripping and opening the bag body 10 is provided between a mounting base 212 and an upper film 11 of the bag body 10. The manufacturing device for manufacturing the reclosable-tape-having bag includes a notching instrument 110 for forming a notch on the bag body 10. The notching instrument 110 includes: a whole-notching instrument 110A for punching the upper film 11, a lower film 12, the open tape 23 and the mounting base 212 to form a tab on a side seal of the bag body 10; and a half-notching instrument 110B for forming an incision on the lower film 12 and a portion of the mounting base 212 corresponding to a position of the open tape 23.
