Juki PLC-1710-7, 1710, 1-Needle, Unison-Feed, Lockstitch Machine
Post-Bed, 1-Needle, Unison-Feed, Lockstitch Machine PLC-1710-7 (Auto Thread Trimmer and Alternating Foot Stroke Adjusting Dial)
This walking foot machine with a thread trimmer utilizes a basic performance that matches best to the sewing of heavy materials such as car seats and furniture. The vertical strokes of the presser foot and walking foot (amount of alternating vertical movement of the walking foot and presser foot) can be easily changed using the large dial mounted on the top of the machine head.
Description
The alternating vertical movement mechanism prevents irregular stitches
JUKI’s alternating vertical movement mechanism maintains consistent presser foot motion despite material weight changes.
The presser foot movement remains stable when sewing heavy-weight materials.
This stability improves walking foot efficiency and prevents uneven material feeding.
Operators can adjust the alternating vertical movement up to 6.5 mm for multilayer materials.
Consistent stitching performance
The PLC-1700 Series features an improved feed mechanism for higher sewing efficiency.
The machine smoothly handles large and heavy materials with reliable feeding.
It produces uniform seams without irregular stitch length variations.
Powerful rectangular-feed mechanism
JUKI’s rectangular-feed mechanism prevents stitch gathering during sewing operations.
The feed system maintains consistent material movement from start to finish.
Reduced feed dog lift minimizes material flopping, noise, and machine vibration.
Dual-tension mechanism
The dual-tension system enables stable sewing with low-count threads under higher tension.
Two tension posts provide better thread control than conventional single-tension systems.
Wide needle range and extended stitch length
The triangular feed rock cam supports consistent sewing with needle counts up to #0.
A larger handwheel increases needle penetration for thick materials.
The machine delivers a maximum stitch length of 12 mm in forward and reverse directions.
Improved basic performance and specifications
The machine reaches a maximum speed of 2500 stitches per minute for higher productivity.
It supports stitch lengths up to 9 mm and 12 mm for the L-type model.
A center-guide presser foot for two needles can be factory installed.
Higher presser foot lift
The presser foot lifts up to 16 mm for easy material handling.
This feature improves efficiency when working with thick or layered materials.
Easy adjustment of alternating vertical movement
A large top-mounted dial allows quick adjustment of alternating vertical movement.
The machine automatically adjusts sewing speed to match the selected setting.
Instant change-over device for alternating vertical movement (DL device)
The DL device instantly maximizes vertical movement for multilayer sewing operations.
Operators activate the DL switch using an arm or knee control.
Safety mechanism
The safety mechanism protects the hook if thread jams occur.
Users can easily reset the system using a dedicated button.
Reliable thread trimming (PLC-1710-7)
The thread trimmer cuts threads ranging from TEX 50 to TEX 135.
Operators can easily adjust knife pressure when changing thread thickness.
