Claim 10

A belt looper apparatus as claimed in claim 1, wherein said folding means comprises a substantially E-shaped coupling block, a shaft having at one end thereof two fingers for folding an end portion of the material in nipping engagement therewith and at the other end thereof a pinion for engagement with a rack movably mounted on the coupling block, and a cylinder pivotally mounted on the holder for moving the shaft axially, the shaft being rotatably mounted in one portion of the coupling block, a rod protruding from the cylinder being mounted in another portion of the coupling block, the shaft being biased by at least one spring.

Claim 11

A belt looper apparatus as claimed in claim 9, wherein a detecting means for seams in the elongated material is mounted on said delivery means.

Claim 12

A belt looper apparatus as claimed in claim 10, wherein said groove forms a grooved cam, whereby said accepting means and said folding means move on curved tracks during their sideward movement.

Claim 13

A belt looper apparatus comprising a delivery means for delivering an elongated material, an accepting means for accepting the delivered material, a cutter for cutting the material secured on said accepting means, a folding means which is located between the accepting means and the cutter and is provided with two fingers, a cycle sewing machine, a guide upon which said accepting means and said folding means are mounted for movement sideways toward the cycle sewing machine, a garment-pressing means mounted on the cycle sewing machine, and a slackening means, the garment pressing means comprising a rod provided with a garment presser on one end portion thereof, a coupled arm having a pair of downwardly-faced brackets and a sidewardly-faced bearing portion with the axis of the latter being above the axis of swing of a pivot arm provided in the sewing machine, and a movable rod adapted to move along the same direction with that of the delivery of the material, the rod and the movable rod being coupled to the coupled arm through an oscillating arm and a movable arm respectively, and said guide being adapted to move along the same direction with that of the movable rod.

Claim 14

A belt looper apparatus comprising a delivery means for delivering an elongated material, an accepting means for accepting the delivered material, a cutter for cutting the material secured on said accepting means, a folding means which is located between the accepting means and the cutter and is provided with two fingers, a cycle sewing machine, a guide upon which said accepting means and said folding means are mounted for movement sideways toward the cycle sewing machine, a garment-pressing means mounted on the cycle sewing machine, and a slackening means, the garment pressing means comprising a rod provided with a garment presser on one end portion thereof, a coupled arm having a pair of downwardly-faced brackets and a sidewardly-faced bearing portion with the axis of the latter being above the axis of swing of a pivot arm provided in the sewing machine, and a movable rod adapted to move along the same direction with that of the delivery of the material, the rod and the movable rod being coupled to the coupled arm through an oscillating arm and a movable arm respectively, and said guide being adapted to move along the same direction with that of the movable rod.

Claim 15

A belt looper apparatus as claimed in claim 12, wherein a detecting means in the elongated material is mounted on said delivery means.

Claim 16

A belt looper apparatus as claimed in claim 13, wherein said accepting means and said folding means move on curved tracks during their sideward movement.

Claim 17

A belt looper apparatus as claimed in claim 12, wherein a folding-back guide means is provided.

Claim 18

A belt looper apparatus as claimed in claim 15, wherein said accepting means and said folding means move on curved tracks during their sideward movement.

Claim 19

A belt looper apparatus as claimed in claim 12, wherein said movable guide is actuated by two cylinders.

Claim 20

A belt looper apparatus as claimed in claim 17, wherein said accepting means and said folding means move on curved tracks during their sideward movement.

Claim 21
