Semi-dry, Unison-feed, Lockstitch Machine with Vertical-axis Large Hook

High and semi-long arm has been adopted.
The long distance from the machine arm to the needle contributes to improved workability.
The LU-2800 Series is a unison-feed, lockstitch machine with a vertical-axis large hook which is provided with substantially improved functions and performance.

Product features

  • Functions for improving seam quality and workability

    The long distance from the machine arm to the needle contributes to improved workability

  • Double tension provided as : standard

    Single or Double can be set easy through Multi-functional 6-string switch, regarding the machine with trimmer.
    (Available for more thick material)

  • Multi-functional 6-string switch (thread trimming switch)

    In addition to the one-touch type reverse feed switch, a multi-functional 6-string switch is also provided. Changeover of the amount of the alternating vertical movement of the walking foot and the presser foot and changeover of the stitch length can be done simply with this one switch.

  • Walking-foot/presser-foot alternating vertical movement mechanism

    The sewing machine has adopted a feed mechanism which keeps the ratio between the amount of the vertical movement of the walking foot and that of the presser foot constant even when the material is changed. The amount of the alternating vertical movement of the walking foot and the presser foot is 9 mm at the maximum. This amount can be set with ease by means of the large dial installed on the upper section of the sewing machine.

  • Higher lift of the presser bar

    A presser bar height of 20 mm is achieved when using the automatic presser bar lifting lever. Thanks to this feature, the process of joining leather and heavy-weight sponges, which are usually used as materials for expensive sofas, can be carried out with ease.

  • Eccentricity of the feed driving cam is adjustable

    Adjustment of the eccentricity of the feed driving cam has been enabled. As a result, the sewing machine is able to perform sewing with the feed that is best-suited to the material and thread used.
     It is no longer necessary to prepare other subclass model sewing machines.

  • New lubrication system

    Lubrication system is powerful and stable even low speed.

  • New bobbin thread spool device

    New bobbin thread spool device is no neccessity of rolling thread manually.

  • Stitch length can be changed over among different lengths

    The sewing machine with a thread trimmer is provided as standard with a 2-pitch dial. One unit of this sewing machine is able to sew different sewing lengths since the sewing length can be instantaneously changed over.

  • 2.0 / 2.7 fold-capacity hook

    The hook which can be adjusted with screw amout of needle guard contact to needle. The needle guard can be easily adjusted. Therefore, it prevents stitch skipping and wear of hook edge.

Basic performance

  • High-torque direct-drive motor is installed

    The sewing machine provided with a thread trimmer has adopted a high-torque direct-drive motor which is suitable for heavy-weight materials. As a result, the sewing machine is excellent at its responsiveness and ensures increased penetration into the material even when sewing multi-layered parts.
    The direct-drive motor system has been adopted by all of the sewing machines with a thread trimmer. As a result, the sewing machine starts up swiftly and promises increased stop accuracy, thereby demonstrating improved responsiveness. 
    In addition, the machine is no longer provided with a V-belt. This means that the adoption of the direct-drive motor is also effective in the elimination of belt shavings. Power is directly transmitted from the motor to the sewing machine, thereby contributing to reduced power consumption. (This sewing machine reduces power consumption by 37% as compared with the conventional models.) Adoption of a direct-driven main shaft and a revamping of mechanism design contribute to remarkably reduced noise. Noise has been reduced by 3.5dB as compared with the conventional model to produce this operator-friendly machine.

  • New-type tank style automatic lubrication mechanism has been adopted

    The oil dropped from the hook and its surrounding sections into the under-cover is filtered to remove dirt and dust and is then returned to the oil tank. 
    This method saves the effort of oiling and reduces oil consumption.
    The remaining oil quantity indicator is provided on the front face of the machine head. Lubrication can be carried out without tilting the machine head.

Cutting-edge Lineup

    LU-2860
    Semi-dry, 2-needle, Unison-feed, Lockstitch Machine with Vertical-axis 2.0 Fold-Capacity Hook

    High and semi-long arm has been adopted. Wide machine bed area contributes to improved workability. Direct-drive, unison-feed, Lockstitch machine with a vertical-axis large hook providing substantially improved functions and performance.

  • LU-2810-7
    Semi-dry Direct-drive, 1-needle, Unison-feed, Lockstitch Machine with Vertical-axis 2.0 Fold-Capacity Hook with automatic thread trimmer
    LU-2860-7
    Semi-dry Direct-drive, 2-needle, Unison-feed, Lockstitch Machine with Vertical-axis 2.0 Fold-Capacity Hook with automatic thread trimmer

    High and long arm has been adopted.
    The machine is suited to the sewing of car seats, sofas and bags. It is a sewing machine provided with dramatically improved workability and functions which are required for sewing large products and extra heavy-weight materials.

  • LU-2828A-7
    Semi-dry Direct-drive, 1-needle, Unison-feed, Lockstitch Machine with Vertical-axis 2.7 Fold-Capacity Hook 
    (needle thread roll-in and shorter - thread remaining type)

    The shorter-thread remaining type LU-2828A-7 is a high-performance sewing machine. It leaves a shorter thread on the material at the beginning of sewing by means of the needle thread clamp device, as well as at the end of sewing by means of the thread trimmer which is provided with a shorter-thread remaining function. This means that manual thread nipping both at the beginning and at the end of sewing is no longer required, thereby helping reduce operator fatigue. Thanks to the adoption of a 2.7-fold hook, the frequency of bobbin thread changing is reduced and workability is improved.

     

  • LU-2818AL-7
    Semi-dry Direct-drive, 1-needle, Unison-feed, Lockstitch Machine with Vertical-axis 2.7 Fold-Capacity Hook with automatic thread trimmer (long-pitch type)

    Semi-dry Direct-drive, 2-needle, Unison-feed, Lockstitch
    Machine with Vertical-axis 2.7 Fold-Capacity Hook with automatic thread trimmer (long-pitch type)

    This model is the most-desired sewing machine for sewing furniture such as sofas. It is best-suited to topstitching with a long stitch pitch.
    During the topstitching process, the longer distance from the machine arm to the bed, in particular, effectively demonstrates the machine's improved workability.
