PURPOSE:To prevent the generation of an uncutting part even in case of a cloth, etc., by constituting the bridging member composed of almost wire rods by connecting it equivalency so that its material placing face becomes flat by a material placing means. CONSTITUTION:The placing means of a caterpillar is constituted with the outer end side of a spiral coil 11(1) being arranged so as to bite each other with one end side of the spiral coil 11(2) composed of the same raw material, with a connection pin 12 being arranged by inserting it into this mutually superposing part with the spiral coils 11(1), 11(2)... in parallel state being mutually continued thus. Consequently it shows such a surface as a honeycomb, there is no ruggedness actually on the face on which a cloth is placed and the defect of the focal point of a laser light going wrong is prevented. |
