Title:
INJECTION MOLDER WITH RUNNER CUTTER FOR MANUFACTURING FASTENER STRINGERS HAVING SYNTHETIC RESIN TEETH
Document Type and Number:
Japanese Patent JPS60232920
Kind Code:
A
Abstract:

PURPOSE: To arrange so that a runner with a spool may be fed to a runner cutter securely and rapidly and cut to a certain length by making an interval between a separation roller and a feed roller equivalent to a distance added with an equal length to a interblade gap between an upper cutter and a lower cutter to the length of a runner.

CONSTITUTION: It is arranged so that a spool 25 of a runner exists between an upper cutter 11 and a lower cutter 10 of the first cutting device when the terminal of the runner 7 leaves a separation roller 5. Also the distance l1 between the starting edge of the runner and the middle of a feed roller 15 of the second cutting device is almost equal to a vertical distance l2 from a blade edge in a position where the upper cutter 11 of a spool cutter has ascended and a blade edge of the fixed lower cutter 10. Thus the runner 7 is smoothly transfered and cut precisely to the length of chips to be recycled.
