- the rubber member supply system 10 has been supplied by a belt conveyor 14 for supplying a long rubber cut material 12 and a belt conveyor 14.
- a cutter (scraper) 16 for cutting the material to be cut 12 and a rubber member transport section 24 for transporting the rubber member 20 cut by the cutter 16 are provided.
- the belt conveyor 14 is capable of intermittent operation, and the cutting material 12 The conveyance is stopped during cutting.
- the cutter 16 has a blade 18 that is cut by, for example, rotation, and is controlled so as to cut the cut material 12 at a fixed length.
- the rubber member transport section 24 includes an endless belt 26 rotatably held by a pulley 25 on the rear end side in the transport direction and by a driving roller (not shown) on the front end side in the transport direction.
- the endless belt 26 On the conveying surface side (outer surface side) of the endless belt 26, the endless belt 26 is arranged in the conveying direction of the endless belt 26 so as to have a rotation axis in the width direction of the endless belt 26 (that is, a direction orthogonal to the conveying direction).
- a large number of rollers (free rollers) 28 and support portions 30 which are located at both ends of the rollers 28 and which also protrude both side edges of the endless belt 26 so as to rotatably support the rollers 28 are provided.
- the belt conveyor 14 resumes the conveyance of the cut material 12, and stops the conveyance at a stage where the cut material 12 has been conveyed by a certain distance. Then, the cutter 16 moves and cuts the cut material 12. In this way, the rubber members 20 cut to the fixed length are sequentially formed.
