Patent ID: 8062454

Claim:
A process, comprising the steps of: feeding at least a single continuous web in a machine direction as a component member of a disposable wearing article being continuously manufactured, feeding continuous elastic members toward at least one surface of said web while said continuous elastic members are oscillated in a cross direction relative to said machine direction, and attaching said continuous elastic members in a stretched state to said one surface in accordance with a desired layout, wherein in the step of feeding said web, the web is fed to a nip between a pair of press rolls substantially being in contact with each other and rotate in said machine direction around respective axes extending parallel to each other in said cross direction; in the step of feeding said elastic members, the elastic members are fed from upstream of said pair of press rolls to the nip between said press rolls via at least one guiding mechanism that oscillates said elastic members in said cross direction, and in the step of attaching said elastic members to said web, the elastic members are attached to said web by means of an adhesive; wherein each of said at least one guiding mechanism comprises: a motor having a rotary shaft extending in a direction crossing said axes and adapted to repeat reversal of its rotational direction; an arm connected directly with said rotary shaft and extending in a direction crossing said rotary shaft, said arm being formed on its distal end with a guiding element adapted for passage of said elastic members, and said arm being adapted to swing around said rotary shaft as said rotary shaft rotates, wherein said arm is formed from a composite material comprising carbon fiber and any one selected from the group consisting of thermoplastic synthetic resin and thermosetting synthetic resin, and has a specific gravity of 1.5 to 1.8 and a bending modulus of 98 to 201 GPa; and at least one feed member located upstream of said rotary shaft as viewed in said machine direction and adapted to direct said elastic members toward said guiding element; and wherein, in the course of running from said feed member to said pair of press rolls via said at least one guiding mechanism, said elastic members are attached to said web while said elastic members are oscillated, at a maximum angular acceleration of 15,000 rad/sec 2 , in said cross direction by said arm connected directly with said rotary shaft so as to repeat reversal of its swinging direction; said process further comprising arranging said axes of said press rolls horizontally, said rotary shaft of said motor vertically, and said arm to extend horizontally from said rotary shaft toward said nip between said press rolls.
