Abstract
An apparatus and method for producing a wearing article of the present invention includes supplying an elastic member; stretching the elastic member; placing the stretched elastic member so that the elastic member spreads across a plurality of first webs divided in a transport direction; making a part of a second web loose in the transport direction while transporting the second web, thereby forming a loose portion; placing the first web, on which the elastic member is disposed, on non-loose portion before and after the loose portion of the second web; and cutting the elastic member between adjacent first webs of the plurality of first webs.
Claims25
An apparatus for producing a wearing article, comprising:
- means for supplying an elastic member;
- means for stretching the elastic member;
- means for placing the stretched elastic member so that the elastic member spreads across a plurality of first webs divided in a transport direction;
- means for making a part of a second web loose in the transport direction while transporting the second web, thereby forming a loose portion;
- means for placing the first web, on which the elastic member is disposed, on non-loose portion before and after the loose portion of the second web;
- and
- means for cutting the elastic member between adjacent first webs of the plurality of first webs.
An apparatus for producing a wearing article, comprising:
- a roller means for supplying a plurality of first webs divided in a transport direction at a predetermined position in a state where an elastic member is placed so as to spread across the first webs;
- rotation means including a plurality of pads for rotating the plurality of pads to continuously transport a second web and approach the roller means at the predetermined position;
- and
- cutter means for cutting the elastic member,
- wherein the rotation means rotates the respective pads of the rotation means so as to have varying circumferential velocities, the respective pads of the rotation means receive the second web at a receiving position upstream from the predetermined position, and after receiving, an interval between the adjacent pads is decreased while the pads are rotated to the predetermined position, whereby a loose portion is formed in the second web,
- the first webs are placed to be stacked on a surface of the second web on a basis of the pads at the predetermined position,
- an interval between the adjacent pads is increased while the respective pads of the rotation means are rotated from the predetermined position to a releasing position downstream from the predetermined position, and
- the cutter means cuts the elastic member in the loose portion while the pads are rotated from the predetermined position to the releasing position.
An apparatus for producing a wearing article, comprising:
- means for supplying a first elastic member, a first web, and a second web;
- means for stretching the first elastic member;
- means for cutting the first web to a predetermined length in a transport direction to form cut first webs;
- means for making a part of the second web loose in the transport direction, thereby forming a loose portion;
- means for putting the stretched first elastic member between the cut first webs and the second web to place the cut first webs on non-loose portions before and after the loose portion of the second web;
- and
- means for cutting the first elastic member above the loose portion.
