Title:
SHEET-FEEDING METHOD AND APPARATUS IN NEEDLING MACHINE SUCH AS TUFTING MACHINE, NEEDLE-PUNCH FELTING MACHINE OR PUNCHING MACHINE FOR PLASTIC FILM
Document Type and Number:
Japanese Patent JPS55130450
Kind Code:
A
Abstract:

PURPOSE: To continuously needle-punch a sheet, by continually feeding and winding said sheet while allowing said sheet to move with needles or to be in stoppage at a needle-punching position during a needle-punching period.

CONSTITUTION: In a sheet-conveyor applied to a needling machine such as a tufting machine, the needle drive shaft 41 is rotated at a pre-determined speed by a drive shaft 4 through a chain 81. On the other hand, a winding roller 5 and a feeding roller 6, whcih are disposed respectively after and before a row of needles 3, are periodically rotated at a desired speed via a non-circular gear wheel 7 which is rotated synchronously with said needle drive shaft 41. Simultaneously, said needles 3 carrying pile strings 33 therethrough are moved up and down via a crank shaft 31, thereby to needle-punch a foundation fabric 21 and to tuft piles through said foundation fabric 21 in cooperation with a looper 34. The displacement (x) of said foundation fabric 21 corresponding to the periodical displacement (y) of said needles 3 is represented by a displacement curve (c) shown in the drawing. Thus, the neelde-punching operation can be performed continuously.
