Method for splicing material and device for supplying material

A device for supplying a material associated with an absorbent article, comprising:

• a dancer unit including an entrance roll and a moving roll;
• a transport section that transports the material in a direction of transport while the material wound around the entrance roll and the moving roll;
• a material splicing section that splices a subsequent material with a preceding material by bonding a leading end portion of the subsequent material with the preceding material,
• the preceding material being the material that is transported;
• a cutting section that forms a fin-like portion of the preceding material upstream in the direction of transport from a bonded portion where the preceding material and the subsequent material are bonded,
• the forming being performed by cutting the preceding material at a position upstream from the bonded portion,
• transport of the material in which the bonded portion and a stacking portion are provided side-by-side along the direction of transport being continued by the transport section while the material being wound around the entrance roll and the moving roll,
• the stacking portion being a portion where the fin-like portion and the subsequent material are stacked;
• and
• a control section that controls transport of the material so that the moving roll is located at a reference position,
• the cutting section cutting the preceding material so that a total length of the bonded portion and the stacking portion is larger than a path length of the material from a downstream end of a winding portion of the material to an upstream end of another winding portion of the material,
• the winding portion being a portion wound around the entrance roll,
• the other winding portion being a portion wound around the moving roll located at the reference position.
