SEWING MACHINE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18522105 titled 'SEWING MACHINE
Simplified Explanation
The abstract describes a sewing machine that suppresses sewing defects by adjusting pressure applied to the to-be-sewn article based on the feeding amounts of feeding belts on either side of the sewing position.
- Sewing machine with a sewing needle, shuttle, presser foot member, pressure adjustment portion, feeding mechanism, belt drive portion, and control portion.
- Feeding belts on two sides of the sewing position are independently driven to adjust pressure on the to-be-sewn article.
- Control portion adjusts pressure of presser foot member based on the difference in feeding amounts of feeding belts on each side of the sewing position.
Potential Applications
This technology could be applied in industrial sewing machines, garment manufacturing, and textile production to improve seam quality and reduce sewing defects.
Problems Solved
1. Sewing defects such as uneven seams, puckering, and fabric shifting are minimized. 2. Consistent pressure on the to-be-sewn article ensures uniform stitching and prevents material distortion.
Benefits
1. Improved sewing accuracy and quality. 2. Increased productivity and efficiency in sewing operations. 3. Reduced material waste and rework due to sewing errors.
Potential Commercial Applications
Optimizing Pressure Adjustment in Sewing Machines for Enhanced Seam Quality
Possible Prior Art
Prior art may include sewing machines with manual pressure adjustment mechanisms or fixed pressure settings that do not dynamically respond to variations in feeding amounts of feeding belts.
Unanswered Questions
How does the control portion determine the optimal pressure adjustment based on feeding amounts?
The control portion likely uses sensors to measure the feeding amounts of feeding belts and calculates the difference to adjust the pressure accordingly.
Are there any limitations to the effectiveness of this technology in suppressing sewing defects?
Potential limitations could include the complexity of the system, maintenance requirements, and compatibility with different types of fabrics or sewing techniques.
Original Abstract Submitted
A sewing machine that suppresses sewing defects is provided. The sewing machine includes: a sewing needing, held by a needle bar and moving back and forth while holding an upper thread: a shuttle, configured to hold a bobbin which is housed in a bobbin case and around which a lower thread is wound, and cooperating with the sewing needle to form a seam; a presser foot member, configured to press a to-be-sewn article at a sewing position directly below the sewing needle: a pressure adjustment portion, adjusting pressure applied to the to-be-sewn article by the presser foot member; a feeding mechanism, where endless feeding belts for feeding the to-be-sewn article from the sewing position to a first direction are disposed on two sides of a second direction orthogonal to a first direction with respect to the sewing position, the feeding mechanism is provided with a belt drive portion, and the belt drive portion independently drives the feeding belts on one side of the second direction with respect to the sewing position and the feeding belts on another side of the second direction with respect to the sewing position; and a control portion, configured to control the pressure adjustment portion to make a pressure of the presser foot member be corresponding to a difference between a feeding amount of the feeding belts on one side of the second direction with respect to the sewing position and a feeding amount of the feeding belts on another side of the second direction with respect to the sewing position.
