Latest Patents
Sahashi's most recent innovations include:
1. **Programmed Pressure Foot Positioning for Control Means Sewing Machine**: This invention addresses the sound of percussion or impact produced by a vertical movement of the pressure foot, which operates synchronously with the sewing needle. It features a specialized sphere exposed through the lower surface of the pressure foot, coupled with a coiled compression spring that prevents unnecessary vertical movement of the fabric, while still allowing horizontal movement. This design eliminates the need for the pressure foot to move vertically as the needle ascends and descends, significantly enhancing sewing efficiency.
2. **Device for Controlling Feeding Quantity of a Sewing Machine**: This device comprises a driver that operates both an upper feed-dog and a lower feed-dog. It includes two setters to establish the feeding quantity for the lower feed-dog and the ratio of feeding quantity between the two feed-dogs. The system is designed with adjusters to fine-tune the feeding quantities based on the preset values and ratios, ensuring precise control over fabric feeding during sewing operations.
