Bag-making and packaging apparatus

摘要

A bag-making and packaging apparatus (1) includes a bag-making and packaging mechanism (5) and a fold formation mechanism (3). The fold formation mechanism (3) is configured and arranged to deform a packaging material (F) from a planar state to a folded state having a cross-sectional shape including a fold portion (FF) formed by three creases, and to feed the packaging material to the bag-making and packaging mechanism (5). The fold formation mechanism (3) may include a conveying path regulating part (31) that defines a part of a conveying path of the packaging material with the conveying path regulating part (31) temporarily bending the packaging material for a plurality of times. The bag-making and packaging apparatus may further include a slanting member (343) for slanting the fold portion (FF) to be generally parallel to a region of the packaging material other than the folding section, and a conveying angle changing member disposed downstream of the slanting member (343).
