Ball for ball game and method for manufacturing the same

To provide a ball for ball game and a method for manufacturing the ball having superior sphericity, an ability to retain its original shape, durability, and soft feel. The fabric layer (12) is formed by sewing with a sewing machine for instance pentagonal first fabric pieces (13) together with composite shaped second fabric pieces (14) in which two hexagons are connected with each other, so that a spherical shape is formed. The marginal edge of the first and second fabric pieces are superimposed in the spherical surface direction, so that corner portions thereof are temporarily attached. Temporary attachment is achieved by inserting the needle into the needle through hole formed in the corner of the first and second fabric pieces, and welding by means of ultra sonic wave, such that the first and second fabric pieces (13, 14) are accurately aligned. The temporarily attached fabric pieces sewn together using a sewing machine along the guiding line (17) for sewing printed beforehand on the surface of the fabric pieces (13, 14).

Systems and methods for assembling components of a fabric-covered prosthetic heart valve

A system and method for assembling a prosthetic heart valve, including a procedure for tightly wrapping fabric around a heart valve support stent. The support stent typically includes alternating cusps and commissures that create a highly contoured undulating outflow edge. The system includes a mandrel for retaining tension without manual assistance in a tubular length of fabric wrapped over the support stent. The mandrel may include an inner clamping mechanism for holding the first end of the fabric tube, a pedestal tube on which the support stent rests and through which the fabric tube passes, and an outer clamping mechanism for holding the free end of the fabric tube. The inner and outer clamping mechanisms include discrete clamps spaced apart 120° from each other that pull the fabric only in the cusps of the support stent. The inner clamping mechanism, outer clamping mechanism, and pedestal are relatively axially movable. Once the fabric is retained over the support stent, the mandrel may be placed in a chuck of a sewing machine system for automatically forming the seam. A small shuttle with bobbin thread reciprocates within a channel inside of the support stent and cooperates with the sewing machine needle to form a lock-stitch in the fabric tube. The mechanization of the fabric covering procedure greatly enhances manufacturing throughput and reduces ergonomic strain on workers.

Sewing machine

The invention provided a sewing machine, improved to automatically switch the sewing machine to the thickness of cloth. This sewing machine includes: a housing having a base plate; a top arm; and a strut for integrating the base plate with the top arm. A metallic presser presses a cloth piece near a stitch forming position. The metallic presser driven by a movable rod is capable of moving between the lift position for releasing the cloth piece and the pressing position for the cloth piece to be pressed. When the metallic presser moves between these positions, the distance of at least one movable rod part from a reference structure fixed to the housing stably changes. The position sensor detects the position of the metallic presser in the pressing position. A control system makes signal connection thereto. The system sets an adjustment variable for the sewing machine depending upon the output value of the position sensor. As a result, the obtained sewing machine automatically performs switching to the thickness of variable cloth piece.
