Problems solved by technology
Therefore, during the conveying process, the continuum rubs against the linear part of the folding base point rod 330, and the frictional resistance generated by it will disturb the conveying state of the continuum, that is, where the first area and the second area of the continuum overlap. Partially, phase misalignment between the first area and the second area is prone to occur
To solve this technical problem, it is necessary to reduce the frictional resistance of the folding base point rod 330 to the continuum, or use the variable roller 400 to adjust the conveying state of the continuum, otherwise it will be difficult to perform the continuous body folding work stably

The present invention relates to a continuous body folding device and a folding method for easily and stably performing continuous body folding work. The continuous body folding device of the present invention comprises: a conveying part, a first folding reference part (30) and a first guide member, wherein the conveying part has a first area (2a) of the continuous body (2) by suction and holding. The moving surface that moves at the same time conveys the continuous body (2) in the longitudinal direction of the continuous body (2); at the first folding reference portion, the first circulation path is along the first virtual surface including the moving surface. The first endless conveyor belt (31) moving in the middle moves the first reference section (31x) adjacent to the virtual line (2x) of the continuum (2) in the same direction as the moving surface at the same speed; the first guide The components are arranged along the first reference interval (31x), and are in contact with the second area (2b) of the continuum (2); The angle formed with the second area decreases as the continuous body (2) is conveyed in the downstream direction of the conveying direction, and the second area (2b) is folded after folding the continuous body (2) with the virtual line (2x) as a reference. Move to the first area (2a).
Description
technical field [0001] The invention relates to a folding device and a folding method for a continuous body, in particular to a folding device and a folding method for folding a belt-shaped continuous body while conveying it. Background technique [0002] Continuum folding device, - which is used in the manufacture of disposable absorbent articles, such as: urine pads, etc. [0003] Such as Figure 7 As shown, it is a perspective view of an existing continuum folding device 100 for manufacturing underpants-type disposable urine pads. The continuum has first and second parts 61 and 62 extending parallel to each other at intervals, and an absorber arranged to straddle between the first and second parts 61 and 62 and bonded to the first and second parts. The continuum is strip-shaped, and is divided into a first region T1 on the side of the first part 61 and a second region on the side of the second part 62 by an imaginary line CL1 extending in the longitudinal direction of th...
