Weft yarn end treating device for shuttleless loom

In a shuttleless loom having yarn inserting means located adjacent a first side of the array of warp yarns from which inserting means a weft yarn is picked into the shed of the warp yarns to weave a fabric, a weft yarn end treating device for treating an end portion of the picked weft yarn which end portion is projected from a second side of the array of the warp yarns, the second side being opposite to the first side and remote away from the yarn inserting means, said weft yarn end treating device comprising:

• conveying means for conveying the projected end portion of the weft yarn in a direction generally the same as the moving direction of woven fabric from a portion adjacent the weave front of a woven fabric, when the projected end portion is held to contact therewith, said conveying means including first belt means which is movable substantially in the same direction as the moving direction of the woven fabric;
• holding means for holding the projected end portion to contact with said conveying means, said holding means including second belt means movable disposed adjacent and along said first belt means, and associating means for associating said second belt means with said first belt means to hold the projected end portion of the weft yarn to contact with said first belt means by the action of said second belt means,
• thrusting means for thrusting the projected end portion of the weft yarn into a location at which the projected end portion begins to be held to contact with the conveying means, said thrusting means being actuated in connection with the operation of said loom;
• and
• cutting means for cutting the projected end portion of the weft yarn in close proximity to a side of the fabric which side corresponds to the second side of the warp yarn array, after the projected end portion is thrust into said location, said cutting means being located between the fabric and said conveying means.

• conveying means for conveying the projected end portion of the weft yarn in a direction generally the same as the moving direction of woven fabric from a portion adjacent the weave front of a woven fabric, when the projected end portion is held to contact therewith, said conveying means including a first rotatable cylindrical roller which is formed at its cylindrical surface with a first continuous spiral groove;
• holding means for holding the projected end portion to contact with said conveying means, said holding means including a second rotatable cylindrical roller which is formed at its cylindrical surface with a second continuous spiral groove, said second roller being disposed in close proximity to said first roller, the second spiral groove of said second roller being located opposite to the first spiral groove of said first roller to form a plurality of spaces therebetween, the projected end portion of the weft yarn being disposed in each space, said spaces being aligned along the longitudinal axes of said roller;
• thrusting means for thrusting the projected end portion of the weft yarn into a location at which the projected end portion begins to be held to contact with the conveying means, said thrusting means being actuated in connection with the operation of said loom;
• and
• cutting means for cutting the projected end portion of the weft yarn in closed proximity to a side of the fabric which side corresponds to the second side of the warp yarn array, after the projected end portion is thrust into said location, said cutting means being located between the fabric and said conveying means.

• conveying means for conveying the projected end portion of the weft yarn in a direction generally the same as the moving direction of woven fabric, when the projected end portion is held to contact therewith, said conveying means including a belt movable in the direction substantially the same as the moving direction of the woven fabric, said belt being loop-shaped and passed on first and second pulleys which are located separate from each other, said first pulley being located adjacent said cutting means;
• holding means for holding the projected end portion to contact with said conveying means, said holding means including a stationary plate member contactable with the surface of said belt, said stationary plate member being secured to the frame of said shuttleless loom and including a higher portion to which the surface of the belt is contactable, and a lower portion which is depressed below said higher portion and from which the surface of said belt is spaced apart;
• thrusting means for thrusting the projected end portion of the weft yarn into a location at which the projected end portion begins to be held to contact with the conveying means, said thrusting means being actuated in connection with the operation of said loom, said thrusting means including a movable rod member swingably supported on the frame of a reed of said shuttleless loom, said movable rod member including upper and lower portions which extend generally oppositely with respect to a portion at which said movable rod member is swingably supported, and a push rod member disposed stationary relative to the frame of said shuttleless loom, said push rod member being strikable against the upper portion of said movable rod member to move the lower portion of said movable rod member so as to carry the projected end portion of the weft yarn into said location;
• and
• cutting means for cutting the projected end portion of the weft yarn in close proximity to a side of the fabric which side corresponds to the second side of the warp yarn array, after the projected end portion is thrust into said location, said cutting means being located between the fabric and said conveying means.
