General

The S-311 electronically controlled, fully programmable eyelet buttonhole machine provides the user with total flexibility and versatility with a wide variety of models. Machine is equipped with new, faster control system, including 20% reduced cycle time, and new larger touch screen display. Optional accessories, especially designed for jacket applications, provide higher cutting flexibility including the desired cutting position. These facilitate the production of buttonholes  in one operation without any follow-up work. 

Features

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.

Programmable Cycle Sewing

Cycle sewing, which is a standard feature on all models, allows up to 21 different buttonholes to be sewn in 47 different programs. For example the operator can set the machine to sew any of the buttonhole styles in any combinations such as 2x eyelet, 1x no eye, 1x eyelet with crossbar. These programs can be easily set by the operator from the control panel.

Ultra Flexibility on Men’s Suit Applications

Thank to our Ultraflex accessories the buttonhole applications on the men’s suits are now very easy. With a combination of the lapel system and the lapel optical sensor – the machine provides the operator with partial cutting of the lapel buttonhole in precisely specified place and automatically recognizes the correct buttonhole from the cycle mode. These new accessories are available only for machines that are equipped with Automatic Cutting Length (ACL) System. Please refer to the Optional Accessories for more details.

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. The operator can set the stitch bite for buttonhole and crossbar finish separately.

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 models are classified according to the trimming mechanism into AF, CT, LTT models. Optional clamp plates have to be used for each machine model to perform the required buttonholes. All threads are trimmed with the exception of the AF (adjustable flybar) model where only the top thread can be trimmed.

Sewing Patterns

The AF and LTT models are capable of sewing the same range of buttonhole types with eye or no eye (open end, basic adjustable flybar, crossbar, round end). All CT models are used only for buttonholes with flybar finishing. To view available sewing patterns please click here. Gimp is applicable in all models, excluding the RDE model, but not recommended when the crossbar type buttonhole is selected.

Application

The S-311 Range can be used for all types of garments that require an eyelet buttonhole, including menswear, ladieswear, jeans, trousers and other outerwear.
