Title:
STITCHING HEAD AND MACHINE FOR PRODUCING REINFORCEMENT FOR COMPOSITE COMPONENT
Document Type and Number:
Japanese Patent JP3805810
Kind Code:
B2
Abstract:
PURPOSE: To produce a sheet-like reinforcement by mechanically compacting superposed plies of thread comprising warp plies and weft plies with a presser-foot to embed a reinforcing thread in a cured matrix through the superposed plies of thread.
CONSTITUTION: In this stitching head for a machine for producing a reinforcement in the form of a sheet for a composite component formed by the reinforcement embedded in a cured matrix, a support 40 for supporting a needle 33 and further supporting a linkage bar 45 to which a presser-foot 43 moving in relation to the needle 33 is fixed is attached to a block 29 mechanically connected to the stitching head. A guide passage 41A for a thread F to be inserted into the needle 33 is penetrated in a rotary support 41 in the support 40. The linkage bar 45 of the presser-foot 43 is pressed down with a compression spring 44A composing of the spring mechanism 44 and held in the support 40 with a stopper 44B. The assembly of the presser-foot 43, the thread guide and the needle 33 can be operated by a cylinder type operation mechanism. The superposed plies of thread comprising warp plies and weft plies are mechanically compacted with the presser foot 43, and the needle 33 is vertically moved to penetrate the thread F in the superposed plies of thread, thereby forming the sheet-like reinforcement without weaving warps and wefts.
