Indexer Unit
The Indexer unit is a special device ensuring automatic sewing of buttonholes with the possibility to set the number of buttonholes and the specific distances between them.
X-Y Electronic Control Motors
This X-Y machine is driven by three stepper motors and an induction motor. The stepper motors control the rotation of the sewing race, the horizontal and lateral movements of the machine. An induction motor drives the needle bar movement.
X-Y electronic control reduces the number of mechanical parts, increases the machine flexibility and provides a quiter operating environment. With fewer parts, the machine is more productive, more reliable with less down-time.
Touch Screen
Touch screen interface is fixed onto the machine table and can be adjusted for operator comfort. The use of easily understood symbols and graphics reduces the amount of operator training time normally required to set buttonhole types and sewing parameters.
The total flexibility provided by the program means that all important machine features including the cycle mode can be selected and sewn by a simple touch on the screen. Please refer to the chart below for more details.
| List of the Major Operations of the Touch Screen |
 |
| Title |
Description |
| Buttonhole Adjustments |
Selection of all buttonhole parameters - eye shape; types of finish; length of buttonhole or flybar and crossbar; number of stitches around eye, in flybar or crossbar; aligning the first and second row of stitches; stitch density |
| Adjustment of Distance between Buttonholes |
Sets the required distance between each buttonhole in mm. |
| Manual Stepping |
Manual stepping from one buttonhole to the next buttonhole |
| Mirror Function |
By activating this function the machine sews buttonholes in one cycle in sequence 1, 2, 3, 4 and next cycle in sequence 4, 3, 2, 1. |
| Indexer Auto Mode |
Auto mode selection - machines sews one cycle from left to right and next cycle fom right to left. |
| Indexer Direction Selection |
Selection of indexer direction either from left to right or right to left. |
| Display Machine Status |
Displays the standard message (ready, busy) or error massage to inform the operator about the machine status |
| Production Counter |
Displays the daily, weekly or continous production |
| Jog |
Moves backward or forward one stitch in manual mode |
| Home position |
Brings the bedplate to the home position |
LED Sewing Lights
The LED sewing lights as a part of the sewing head to illuminate the sewing area better.
Electronic Stitch Bite Adjustments
The electronically adjustable stitch bite provides further programming of the two basic sewing widths; 2,1mm and 2,7 mm; within the range of ± 0,3 mm.
Submerged Sewing Head
Submerged Sewing Head reduces the noise level significantly and allows the operator to handle the garments more ergonomically, which means less operator fatigue.
Pneumatic System
Pneumatic System controls are used for material clamping, cutting, fabric spreading, tension release and thread nipper. On the thread trimming models, the shears are also activated by pneumatics.
Sewing Speed up to 2,000 spm
The sewing speed is adjustable from 1,000 – 2,000 spm on the touch screen. The sewing speed can also be adjusted at the start and end position as well as around the eye to ensure excellent sewing quality even on more difficult materials.
Waste Material Removal and Suction System
The waste material removal & suction system help to keep the working environment cleaner by removal of the cut-off threads and cut-off eye material from the sewing area into a waste bag. This pneumatically controlled system prolongs the knife lifetime and provides our customer with better buttonhole cutting.
Improved Lubrication System
The improved lubrication system ensures quicker oil distribution on the critical parts of the machine immediately after turning the machine on.
Model Classifications
The S-311 Indexer models are classified according to the trimming mechanism into AF and CT and its application.
Sewing Patterns
The AF and CT models are capable of sewing the same range of buttonhole types with eye or no eye (open end, basic adjustable flybar, crossbar, round end).
