Performance and Variants
- Standard Operation: The base M1 model uses a bottom-feed mechanism and a standard hook.
- Advanced Features: While the base version is often manual, specialized subclasses (like the M1-13) can include automatic functions such as thread trimming, needle positioning, and automatic back tacking.
- Motor Options: It can be equipped with either a traditional clutch motor or a modern, energy-saving servomotor for quieter operation and better needle control.
The Siruba L818F-M1 utilizes a drop feed mechanism (also known as bottom feed), which is the standard system for most high-speed industrial lockstitch machines
How the Feed Mechanism Works
In this system, three main components work together to move the fabric: [
1]
- Feed Dog: This is a set of metal teeth (part #D701 for the M1 model) that rises through the needle plate to grip the fabric from the bottom.
- Presser Foot: It provides downward pressure to hold the fabric against the feed dog so it can be moved forward effectively.
- Throat/Needle Plate: The flat surface that the fabric rests on, featuring a slot for the feed dog to move up and down.
Key Features of the L818F-M1 Feed
- Feed Dog Height and Tilt: You can adjust both the height and the tilt of the feed dog to suit different fabric thicknesses and to prevent puckering or uneven feeding.
- Feed Timing: The timing can be adjusted to ensure the fabric moves at the exact moment the needle is out of the material, maintaining consistent stitch length even at high speeds of up to 5,000 stitches per minute.
- Reverse Feed: It includes a responsive, light-to-operate lever for immediate back-tacking to secure the ends of your seams.
- Adjustment Dial: The stitch length is controlled by a large feed regulating dial, which is designed for easy adjustment during operation.
