Screw coupling strip use in a continous screw tightening machine

Abstract

To present a screw coupling strip having a drill screw and a seal washer assembled in a screw holding belt, capable of tightening the screw by using an existing screw holding belt assembling only the drill screw and an existing continuous screw tightening machine, in which the screw holding belt has enough size and strength for allowing to pass the screw head part. A screw coupling strip 1 includes a screw holding belt 2 having intermittent feed notches 22 provided at specified pitches along the lateral edge of a belt main body 21 made of a belt-like body of synthetic resin, and having screw holding parts 23 provided at same pitches as the intermittent feed notches 22 in the longitudinal direction of the belt main body 21, a drill screw 3 having a screw shaft part 31 inserted in the screw holding parts 23, and having a screw head part 33 held passably in the screw holding parts 23, and a washer 4 assembled in the screw shaft part 31 inserted in the screw holding parts 23, in which the holding belt 2 is disposed between the screw head part 33 and the washer 4. FIG. 2.

1 . A screw coupling strip used in a continuous screw tightening machine comprising:
 a screw holding belt having intermittent feed notches provided at specified pitches along the lateral edge of a belt main body made of a belt-like body of synthetic resin, and having screw holding parts provided at the same pitches as the intermittent feed notches in the longitudinal direction of the belt main body,   a drill screw having a screw shaft part inserted in the screw holding parts, and having a screw head part held passably in the screw holding parts, and   a washer assembled in the screw shaft part inserted in the screw holding parts,   wherein the holding belt is disposed between the screw head part and the washer.   
   
   
       2 . The screw coupling strip used in a continuous screw tightening machine of  claim 1 , wherein an interval for allowing the screw coupling strip to pass through a belt guide part of the continuous screw tightening machine is provided between the downside of the screw holding belt and the washer. 
   
   
       3 . The screw coupling strip used in a continuous screw tightening machine of  claim 1 , wherein the washer is a seal washer having a sealing member adhered to a metal washer. 
   
   
       4 . The screw coupling strip used in a continuous screw tightening machine of  claim 2 , wherein the washer is a seal washer having a sealing member adhered to a metal washer.
