  2. Product overview What is the automatic sewing machine AB-1351? It is a JUKI's unique flexible 1-needle automatic belt loop attaching machine for sewing belt loops of consistent quality. This is the world's first 1-needle automatic belt loop attaching machine that is provided with seven different sewing patterns. Advantages of the automatic sewing machines Production without requiring skill Improved quality Increased productivity

  3. Product overview Belt-loop feeder unit Belt-loop feeder unit This unit cuts belt-loops into fixed dimensions, folds both ends inside and places them under the needle. The belt-loops themselves are sewn in the previous process. LK1961 LK1961(←LK1900A) This machine head sews “top and bottom bartacks” on the belt-loops supplied by the belt-loop feeder unit. Operation panel (IP420) Operation panel (IP420) This panel is used to change various settings and download and/or upload data. (CompactFlash card and/or USB thumb drive can be used as a medium for inputting/outputting data.)

  4. Main features 1.The sewing machine is able to sew various types of belt-loops utilizing its seven different sewing patterns. JUKI ORIGINAL Production without requiring skill The original sketches are “P4 No.1 to No. 7" on the attached sheet.

  5. Main features NO.1 NO.2 NO.3 NO.4 NO.5 NO.6 NO.7 ・The finished belt loops are patterns No. 5 and No. 7 illustrated in the above figures. 　　　　　　　　　　　　　　　　　　　・The other belt loop patterns are not yet finished and need to be processed in the subsequent process. The AB-1351 is mainly intended for slacks and casual pants.This model is not suited to the sewing of belt loops on hard materials (thickdenim in particular) according to the shape of belt loops.(The maximum thickness of a belt loop that can be sewn is 1.8mm.)

  6. Main features 2-1.Improved quality and increased productivity are promised! Example: Sewing pattern No. 4 Improved quality Increased productivity In the case of manual belt-loop attaching, the operator folds the edges of the belt loops inside with his/her fingers to rough non-uniform dimensions and sews them on garments. In the case of the AB-1351, the operator is only required toplace the material on the machine and press the switch to continuously sew consistent-quality belt-loops. Additionally, with the AB-1351, it is not necessary to cut the belt-loop material into certain dimensions, thereby contributing to labor-saving. Process which is not required.

  7. Main features Increased productivity 2-2. To achieve increased productivity! One operator can operate to two AB1351 units at a time!! * Condition: The number of stitches (the 1st and 2nd bartacks) 42 zigzag stitches each Also refer to "P7attended two units."

  8. Main features JUKI ORIGINAL 3. Twin-drived belt-loop feeding mechanism The belt-loop drawing clamp and the belt-loop pushing roller operatesynchronously with each other (to correct their movements in relation to each other), thereby ensuring accurate belt loop lengths even when using soft and elastic materials. (This mechanism is JUKI's unique twin-drive system.) Clamp which draws belt loops Roller which pushes out belt loops Low tension Such a high tension as to possibly damage the belt loops.

  9. Main features 4. High-performance and highprecision belt loop clamp mechanism ★The belt loop feeder mechanism and the sewing machine head are assembled on the integral mounting base (unit base), thereby preventing them from slipping out of position. LK1900A machine head installing position Belt loop feeder unit installing position Mono-mounting base (unit base)

  10. Main features 5. The machine is installed with the LK-1961, which has one of the highest quality models. The machine is installed with a machine head which has been developed by modifying the highly-reliable LK1900A as the base, In the case of sewing pattern No. 4, for example, three bar tacks can be sewn with different sewing shapes, numbers of stitches, thread tensions and sewing speeds. (Maximum sewing speed: 2500 sti/min) In addition, the feed mechanism is newly controlled by an encoder to help reduce bar-tacking deformation . The “grease joint (provided as standard)" used in the oscillating rock shaft pin section can now also be used in the main shaft crank.

  11. Main features 6. User-friendly operation panel By the IP-420 operation panel, the belt loop shape or sewing pattern can be changed and the sewing positions and other sewing conditions can be programmed with ease through the operation panel. The operation panel supports 14different languages.： Chinese（2kinds）・ English・French・ German・ Indonesian・ Italian・ Korean・ Portuguese・ Russian・ Spanish・Turkish・Vietnamese ・Japanese Number of bartacking patterns stored in its memory: 9 kinds . 6 Linear bartackings　　　：(12-, 15-, 21-, 28-, 36-, 41-stitches) 3 Zigzag bartackings　　：(28-, 36-, 42-stitches) Size (X direction: 6 - 23 mm; Y direction: 0or 1 - 3.2 mm) The maximum number ofbelt-loop patterns that can be stored in its memory: 99 patterns Cycle sewing: Max. 20 cycles (30 patterns per one cycle) The machine stores bartacking shapes 200 patterns or 20,000 stitches at the maximum. It is possible to be created by the PM1 .

  12. Main features 7. The position of starting switch can bechanged according to the sewing specifications. Sub-tableｓ サブ テーブル Starting switch for sewing belt-loops on waistbands: (Press with the right-thumb.) The sub-tables are to be installed. Starting switch for sewing belt-loops on garment bodies: (Press with right-hand.)The sub-tables have to be removed. The starting switches for sewing belt-loops　　　　　　　　　　「on waistbands」and 「on garment bodies」are both provided as standard.

  13. Main features 8. Insert belt loops from the front side! Belt loops are to be inserted from the front side of the main body of the sewing machine. The operator is, therefore, able to visually check the belt loop state whenever necessary during sewing. 9. Oil stains on sewing products are eliminated. The machine is installed with the modified semi-dry LK1900A .The belt loop feeder unit uses a grease lubrication system (with JUKI Grease A). This means that the sewing products are no longer stained with excess oil. (A grease run-out warning sign appears on the panel .)
