Crewless Solution for the Double-Fold
Hemming of the Shirt Front Placket


The entire process of the double-fold hemming of dress shirt’s
under front placket : �@ Loading → �A Setting → �B Folding →
�C Stitching → �D Heat Pressing → �E Stacking : is now fully automated and uncrewed.
The highest quality of stitches is guaranteed thanks to YUHO’s
proprietary Bobbin Thread Backtensioner Technology.

For the Double-Fold Hemming of the Shirt Front Placket	U-4009-E/AUT covers the whole process of making the shirt’s under front placket: �@ Picking up the front panel one by one → �A Positioning the front panel in the right place → �B Double-fold hemming → �C Stitching → �D Heat pressing → �E Stacking: performing automatically. It can handle the materials with vertical stripes, allowing the double-fold hemming to align the stripes*1. Thanks to its revolutionary double-fold hemming mechanism, instead of the conventional binder/hemmer tool, operators can freely set the placket width. Note: Manual operation is required for the stripe alignment process.
Auto Loading Unit Enables Crewless Operation	The auto feeder section employs 4 x adhesive tapes to guarantee secure and stable picking of materials one by one. Just 0.2 mm of the adhesive surface is automatically supplied and rolled up whenever it picks each material up. The operator can set the locations of picking up/releasing precisely and instantly by inputting on the touchscreen. Each feeder unit uses 2 x adhesive tapes, and the positions of 2 x tapes can be adjusted easily within the range of 70 〜 120 mm intervals. Auto loading unit has two sets of feeder units, and the locations of feeder units can be freely adjusted within the range of 25 〜 500 mm intervals. This system realizes the most reliable feeding, as well as the highly accurate positioning of materials covering a variety of shapes and sizes.
Exquisite Stitch Quality Ensured by the Bobbin Thread Backtensioner Technology	After the double-fold process, the material is stitched perfectly without puckering thanks to YUHO's proprietary “Bobbin Thread Backtensioner Technology” (patented in Japan).
Set Placket Width Flexibly	Since the onboard double-fold system automatically sets the specified placket width just by entering the width on the LCD touchscreen, no custom-made gauge replacement is required.
Intuitive Operation with LCD Touchscreen	Besides the placket width, the operator can set or change various functions and parameters of devices instantly just by touching the LCD. This machine's Intuitive touchscreen system allows hassle-free operation, even for the lessexperienced beginner workers.
From Full Double Fold to Single Fold	The material is steadily double-folded with lightning-fast actions by the unique folding device while securely staying on the table thanks to the powerful built-in vacuum suction functionality. Then, the guide rail transports the material under the needle while holding it tightly, and the material is immediately stitched.
Auto Loading without Positioning	If the material has vertical stripes and the alignment with the stripes and the folding lines is required, “Auto” / “Manual” mixed operation is ideal In that case, the auto feeder picks the material up one by one, and it releases the material near the double-fold mechanism so that the machine allows the operator to carefully position the material manually, referring to the marking light (optional). This operation mode can be activated instantly just by pressing the button on the touchscreen.
Material Tray with Lift Keeps Same Height	The lift-type tray of the auto-loading unit supports the materials with a maximum size of 750 mm (W) x 300 mm (D), and the loadable amount of content up to a height of 180 mm. The lift always detects the height of the stack, and automatically lift it so that the top of the material always keeps the same height. The auto loading unit automatically stops operation when the tray is empty. In addition to the shirt’s front placket, U-4009 is also useful for the hemming of small items such as short sleeves and shirt’s pockets. By piling up the materials side by side in two rows on the tray, two sets of auto feeder units pick up and release two pieces of material simultaneously, then the remaining processes: double-fold hemming → stitching → heat pressing: are also made with two pieces simultaneously. During the stitching process of the previous material, the auto feeder units pick up and transport the next material, and standby near the double-fold mechanism. It allows the new material to be placed at the double-fold mechanism as soon as the previous material and guide rail is gone and the double-fold mechanism is free. This design concept guarantees the most efficient overlapping workflow.
Also for the Shirt Upper Front Placket	As long as the front placket is made with a one-piece structure (as shown on the above drawing), the U-4009 is also useful for the production of the upper front placket, just by changing the setting of Stopper/Ruler. Although the extra stitching process B is required separately, this solution has advantages such as ease of plaid matching (horizontal stripe) and ease of inserting interlining.
Heat Presser with Vacuum Suction	After the double-fold process, both left and right sides of the front placket are steadily held down by the guide rail and transported under the needle for stitching, then transported again under to the heat pressing area. The guide rail releases the material while the vacuum suction keeps the material right under the heat pressing element, and it goes down and presses the material.
Crewless Operation Completed with the Stacker	After the heat pressing process, the materials are automatically piled up by the stacker device, and the crewless production process of the doublefold hemming of the shirt front placket, from the beginning (loading) to the end (stacking) is completed. Note: Stacker is not effective in case of handling small items such as short sleeves and shirt pockets.
Inverter for Vacuum Suction	It allows the operator to adjust the intensity of vacuum suction.
Thread Breakage Detector (T.B.D.)	It detects the breakage of needle thread and minimizes the loss of materials.
