A prepreg automatic layering device includes a rotary die-cutter, a cutting mechanism and a control device. The rotary die-cutter, by cutting a prepreg sheet only in the width direction, cuts out a prepreg cut-out section in which a prepreg cut section and an unnecessary portion are integrated. The cutting mechanism is disposed before a layering stage, and separates a portion corresponding to the prepreg cut section and a portion corresponding to the unnecessary portion by cutting the prepreg sheet in the direction in which the prepreg sheet is conveyed. The control device controls the cutting mechanism.

A prepreg sheet attached with a protective sheet is placed on a mounting table to partially overhang. An angle between an edge side direction of an edge section of the mounting table on which overhanging is performed, and a fiber direction of the prepreg sheet, is then set large enough. Overhanging part is physically impacted in a direction to bend fibers of the prepreg sheet to partially peel the protective sheet from the prepreg sheet. A part of the protective sheet peeled from the prepreg sheet is hold and the protective sheet is peeled from an entire surface of the prepreg sheet. A method of peeling a protective sheet from a prepreg sheet more efficiently without damaging the prepreg sheet and an apparatus for peeling to be used therein are provided.

A clamp installation apparatus includes a robot arm pedestal having a rotary table; a robot arm installed on the rotary table of the robot arm pedestal and having a plurality of arms and a plurality of joints; a robot hand installed to a forefront arm of the plurality of arms; and a control device. The robot hand includes: a clamp holding section configured to hold the clamp; a fastening section configured to fasten an engaging section of the clamp to give a clamp force to a work; and a measuring section configured to collect position data of a predetermined member of the clamp. The clamp can be automatically installed and removed. Also, the heat curing can be carried out in the condition to have installed the clamp.
