GS-SE252Z 12G 52-Inch Economic-Double System Waste-Free Sweater Knitting Machine

·Bottom-Up Comb System: Direct Cast-On Without Sealing Yarn
The defining upgrade of the GS-SE252Z over a standard double system machine is the integrated bottom-up comb system, available in compound needle type or no-waste-yarn type configurations. Conventional flat knitting machines require a section of sealing yarn to be knitted before the main fabric begins, providing the initial loop fixation needed for take-down tension to develop. This sealing yarn must subsequently be removed during finishing, consuming extra yarn and adding post-knitting labor. The GS-SE252Z's bottom-up comb grips the initial loops directly and applies downward tension from the very first course, completely eliminating the sealing yarn knitting and removal process. The no-waste-yarn comb variant reduces waste yarn consumption to near zero — a meaningful material cost saving for factories working with high-value fine-gauge yarns at scale.
·Scissor and Clamp System: Automatic Single-Piece Fabric Release
The GS-SE252Z is equipped with left and right scissor clip assemblies that can be programmed to operate synchronously or independently. Upon completion of each knitting piece, the scissors automatically cut the yarn and the clamps secure the yarn end, allowing the finished fabric panel to fall away cleanly without operator intervention. This automatic release function reduces the time operators spend waiting at each machine for piece removal, enabling a single operator to manage a greater number of machines simultaneously in a multi-machine production floor and improving overall labor efficiency. The synchronized or independent operation modes of the scissor clips can be selected according to the stitch structure and panel configuration of each style, balancing operational convenience with yarn conservation.
·Double System Knitting Efficiency and Drive Architecture
The GS-SE252Z maintains the economic double system single-carriage configuration, completing two knitting passes per carriage traverse and delivering substantially higher output per unit time than single system machines at equivalent carriage speeds. Maximum knitting speed is 1.5 m/s, supported by a synchronous belt drive system controlled by an AC servo motor. The synchronous belt delivers high transmission precision with low maintenance requirements, sustaining stable, low-vibration, low-noise operation through extended high-speed production cycles.
·Direct Selection Needle Bed and Fully Motorized Cams
The direct selection needle bed drives each needle's selection action via direct computer control, eliminating the intermediate mechanical linkages of conventional indirect selection systems for faster response and higher precision — particularly advantageous in complex jacquard and high-density pattern knitting. The fully motorized cam system uses servo motor actuation to achieve precise, real-time cam position adjustment during machine operation, with high positional repeatability supporting flexible switching between multiple styles and gauges. An optional insert-type needle bed is available for operations requiring extended needle bed service life, reducing long-term consumable replacement costs in continuous high-intensity production.
·Stitch Density, Racking, and Needle Selection
Stitch density is controlled by a stepping motor with subdivision technology, providing 128 adjustable levels (switchable to 32 levels) over a range of 0 to 650, accommodating the full spectrum from heavy woolen constructions to fine fashion knitwear. The racking system is driven by an AC servo motor with a range of 2 inches and fine-tuning capability, enabling precise transfer and fully fashioned shaping with clean, symmetrical edges. The needle selection mechanism is computer-controlled via an electromagnetic system, delivering stable and efficient needle actuation at full operating speeds.
·16 Yarn Carriers and Flexible Color Management
Sixteen yarn carriers are distributed across four guide rails on both sides of the needle bed, shiftable to any needle position. This expanded carrier count provides ample color management capacity for multicolor jacquard and intarsia knitting, allowing smooth color transitions without frequent production stops for carrier changes. The configuration supports agile switching between multi-color, small-batch styles — well suited to the fast-turnaround, high-variety demands of contemporary knitwear markets.
·Take-Down, Protection, and Control Systems
The take-down roller uses stepping motor control with 128 tension levels adjustable from 0 to 100, enabling precise tension calibration for each fabric construction to prevent distortion and weft bow. The protection system monitors continuously for yarn breakage, float yarn, knots, rewinding errors, end of knitting, racking return failure, needle breakage, and safety door status, triggering automatic alarm and machine stop upon any fault detection. The control system features an LCD display with 256MB memory and USB input, storing large numbers of pattern files for rapid changeover, with all parameters adjustable in real time during machine operation. Multi-language support including Chinese and English is standard. The machine operates on single-phase 220V power with a power-off memory function that preserves the current knitting state through unexpected outages, enabling seamless resumption from the interruption point upon power restoration.
