Computer-controlled, Dry-head, Lockstitch Sleeve Setting Machine with Multi-programming Device DP-2100   The DP-2100 is able to easily carry out sleeve-sewing processes, which are regarded as the most difficult, promising a higher finished-seam quality. DP-2100         An excellent new type belt feed mechanism Thanks to JUKI's unique right-and-left independent drive system of the top feed belt, right and left feed amounts can be adjusted separately. This prevents the material from slipping out of position, thereby sewing sleeves with a consistent seam allowance.     The machine comes provided with a mechanism for moving the belt feed and intermediate presser up and down alternately, enabling it to eliminate tucks produced at the sleeve cap as well as irregular puckering produced in the neighborhood of the sleeve cap.     By introducing the belt feed, the machine reduces scratches to the material made by the feed.     The machine has solved the problems of conventional sleeve-attaching machines. The introduction of active-tension enables the separate setting of suitable thread tensions for sewing sleeves on a portion-by-portion basis. This prevents an inadequate thread tension at a portion where the shirring amount is large or an excessive thread tension at a portion where the shirring amount is small. In addition, specified tension settings can be stored in the memory on a pattern-by-pattern basis and can be reproduced with ease.         New type belt feed mechanism   Alternating vertical movement mechanism   Active tension mechanism Color panel, IP-200C, with upgraded operability Since the machine comes with a touch-sensitive operation panel with a color LCD, data required for sewing, such as the shirring amount, needle thread tension and stitch pitch can be entered with ease.     Data can be saved and transferred by means of SmartMedia. As a result, sewing machines in a factory or in subcontracted factories are able to sew sleeves using the same data.     The operating screen gives a graphic display of an armhole. The operator can, therefore, easily confirm the portion to be sewn and enter/edit data. Operation mode selection is enabled The operation mode of a single machine can be changed over between manual, semi-auto and full-auto according to the ease of use for each operator. SmartMedia IP-200C Dry-head sleeve sewing machine The DP-2100 is the world's first sleeve sewing machine that has adopted the dry-head technology, which does not need oiling. The machine protects the sleeve sewing process, which determines the quality of men's and ladies' garments, from troubles such as oil stains. No need for lubrication facilitates maintenance. Highly-reliable direct-drive system The machine comes with the direct-drive system, in which a compact AC servomotor is directly joined to the main shaft. It offers a quick startup, increased stopping accuracy and excellent responsiveness. Increased lift of the presser foot An increase in the lift of the presser foot facilitates placement of the material under the presser foot as well as the removal of a finished portion. Stitch length is increased The maximum stitch length has been increased to 6 mm. With this large stitch length, an adequate shirring amount is ensured even when a heavy-weight material is used. Many different data input features help the machine perform high-quality sleeve settings quickly and accurately. Smoothing function The machine prevents an abrupt change in the shirring amount at the sewing-step changing point by utilizing a smoothing function. This upgrades the finished quality of the seams.       Correction pitch setting function The stitch pitch can be changed on a portion-by-portion basis. Seam grinning can be prevented by decreasing the stitch length at a portion where the shirring amount is large.             The starting position of the shirring program can be changed. It is possible to change the starting position of the program entered. This enables the armhole display shown on the LCD to bear a close resemblance to the armholes of actual sewing products.   In addition, the machine comes provided with various data inputting features, such as teaching, grading and mirroring for the easy programming of sewing data and for improved operating efficiency. Teaching function Total sewing length is stored in the memory when sewing the portion between notch markes. This enables the quick and easy programming of sewing data. Grading function When basic data is entered, the data is developed on a size-by-size basis. This helps save the operator from future program entering work Mirroring function When a program for sewing either sleeve is entered, a program for sewing the remaining sleeve is automatically created. This helps save the operator from program entering work. It is also possible to incorporate a change made to either sleeve sewing program into the remaining sleeve program by means of the mirroring function.
