Beads threading machine

Abstract

To provide a beads threading machine with which a thread can easily be put through a plurality of beads of various shapes, the beads threading machine comprising supporting portions which are disposed at predetermined intervals in a circumferential direction to thereby support annular projecting portions of the beads, a thread holding portion which is disposed at one end side of the row of supporting portions, an insertion member having at a distal end thereof a hook portion, wherein by rotating the rotary plate in a forward direction, the insertion member is inserted through the beads to thereby dispose the hook portion in the thread holding portion, whereas by rotating the rotary plate in a reverse direction, a thread is caused to be hooked on the hook portion so that the thread hooked on the hook portion is put through the bead holes.

1 . A beads threading machine for threading a plurality of beads each having a bead hole which passes therethrough and annular projecting portions which project outwards from end portions of the bead hole, the beads threading machine comprising:
 a plurality of supporting portions which are disposed at predetermined intervals along a circumferential direction of a circular main body on the main body to thereby support the annular projecting portions of the beads;   a thread holding portion which is disposed at one end side of the row of supporting portions which is disposed circumferentially;   an insertion member having at a distal end thereof a hook portion on which a thread disposed in the thread holding portion is hooked;   a guide path for guiding the insertion member at the other end side which is opposite to the end side of the row of the supporting portion which is disposed circumferentially where the thread holding portion is disposed;   a rotary plate having a fixing portion where a rear end of the insertion member is fixed; and   an accommodation path for accommodating the insertion member so that the insertion member follows a circumferential edge of the rotary plate, wherein   by rotating the rotary plate in a forward direction, the insertion member is inserted through the bead holes in the plurality of beads which are supported on the supporting portions to thereby dispose the hook portion in the thread holding portion, whereas by rotating the rotary plate in a reverse direction, a thread disposed in the thread holding portion is caused to be hooked on the hook portion so that the thread hooked on the hook portion is put through the bead holes.   
     
     
         2 . A beads threading machine as set forth in  claim 1 , comprising a thread pick-up plate which is detachably attached at a thread exit side of the row of supporting portions which is disposed circumferentially, and wherein
 the thread pick-up plate has a holding portion for holding the tread below an opening through which the insertion member is inserted.   
     
     
         3 . A beads threading machine as set forth in  claim 1 , wherein the insertion member has a strip-like shape in which a width measured in a vertical direction of the main body is larger than a thickness measured in a radial direction of the main body. 
     
     
         4 . A beads threading machine as set forth in  claim 1 , wherein the supporting portions are made detachable. 
     
     
         5 . A beads threading machine as set forth in  claim 1 , wherein a base plate on which the supporting portions are placed is made replaceable. 
     
     
         6 . A beads threading machine as set forth in  claim 1 , wherein the supporting portions are made movable in the circumferential direction. 
     
     
         7 . A beads threading machine as set forth in  claim 2 , wherein the insertion member has a strip-like shape in which a width measured in a vertical direction of the main body is larger than a thickness measured in a radial direction of the main body. 
     
     
         8 . A beads threading machine as set forth in  claim 2 , wherein the supporting portions are made detachable. 
     
     
         9 . A beads threading machine as set forth in  claim 2 , wherein a base plate on which the supporting portions are placed is made replaceable. 
     
     
         10 . A beads threading machine as set forth in  claim 2 , wherein the supporting portions are made movable in the circumferential direction. 
     
     
         11 . A beads threading machine as set forth in  claim 3 , wherein the supporting portions are made detachable. 
     
     
         12 . A beads threading machine as set forth in  claim 3 , wherein a base plate on which the supporting portions are placed is made replaceable. 
     
     
         13 . A beads threading machine as set forth in  claim 3 , wherein the supporting portions are made movable in the circumferential direction.
