Denim Sizing

Carefully crafted spun products for every solution
Denim Sizer

The GSSM-100 series line of spun sizing machines are all designed to optimize weaving efficiency. The “D” model is specifically configured to meet the demands required by denim yarns. Heavy duty construction throughout, vertical exit size box which eliminates hard size marks, unique “Uni-Dry” drying section configuration which provides even moisture control of the entire yarn sheet and remote head end for increased operator access/safer operation. The drive and control system use the latest in technology to offer the best performance, most dependable service and easiest operating system available. With a proven history in denim sizing which leads the industry, our customers (both new and repeat) benefit from the highest possible weaving performance to maximize profits.

Denim Beam Creel

Offers multi-beam creels which use section beams made on a direct warper or from a long chain beamer when running rope dye yarns. The creels are designed to group four beams together with walkway access between each 4-beam cluster. The yarn is threaded down to the bottom of the creel and then guided under the walkways to the front of the creel. Heavy duty, structural steel is used to support the beams. The yarn sheet tension is controlled using load cells at the entrance to the size box to automatically control the tension in all running conditions (full to empty beam and accel/decel conditions).

Denim Sizing Box

The UKIL eXpert Squeezer size box is designed to provide consistent, quality squeezing of the yarn as it passes through the box. The unique three roll configuration achieves the effect of a “double dip – double nip” execution. The yarn exits the squeeze roll by a perfect tangential nip which reduces yarn hairiness and also gives the operator 360° access to the size box. Hard size marks caused when the machine stops are eliminated by the use of the nip pool and size circulation system. Once the yarn comes in contact with the size, it’s always in a hot moist environment preventing the size from drying even when the machine stops. The framework is all stainless steel construction and all internal surfaces of the size pan are Teflon coated for easy/fast cleaning to reduce size build-up. Two roll dry feed assembly delivers the yarn to the size box and is automatically tension controlled using a load cell roll.

Drying Section


The UKIL eXpert Dryer, cylinder drying section is designed to provide consistent, quality drying of the wet yarn as it passes through the drying section. The yarn exits the size box and passes vertically into the drying section, which increases access to the yarn sheet and offers the least stressful path to the drying cylinders. Our drying section configurations are determined by the application, we have numurous layouts to fit any styling need with unique designs to ensure even drying throughout the drying proccess. We also have a wide range of methods to drive the cylinders with single motor, multi-motor and combination driven/freewheeling systems. All designs are configured to minimize the tension/stretch of the yarn sheet to ensure the loom beam has the highest possible performance in weaving.

Spun Head


The UKIL eXpert Winder is designed to provide consistent beam winding performance, stable and consistent tension control, and easy, safe use to the operator. Heavy duty steel fabrication eliminates flexing common to many designs. Large frame rails and cross members are matched to the expected loads and working width required for the application. The head and tailstocks move on a large diameter, heavy wall main support tubes with intermediate frame supports. Head and tailstocks can be moved individually or simultaneously to adjust the loom beam position in the winder. New beam startup is an operator “hands off” experience. The operator will tape the yarn sheet to the beam and press the run button. The control system takes care of wrapping the yarn on the core, applying tension, and ramping back up to speed. No operator adjustments are required. This is a safer and more precise method. Weaving can continue to the last meter. Yarn waste at the beam start is eliminated and start up is quicker.

Spun Drive/Control


The UKIL drive/process control system utilizes the latest in hardware and software technology to offer the best performance, most dependable service and easiest system to operate available. A color touchscreen is used to display operating conditions and initiating commands. The graphic program is specialized for sizing machine operation with easy to understand symbols and illustrations. The software includes a machine control program running on the PC under Microsoft Windows 7 with a real time extension. Control software is IEC 61131-3 compliant, the operator interface utilizes Microsoft Visual Basic. The Ethercat communication is a fast, reliable, “state of the art” control system for the 21st century.
