Overview

This document provides detailed technical specifications, features, and options for various models of multi-gauge knitting units, including CMS 502 ki, CMS 520 ki C, CMS 530 ki series, CMS 730 ki T, CMS 822 ki, CMS 933 ki, and TT sport models. It covers mechanical, electronic, and operational parameters essential for machine selection and operation.

1. Machine Carriages and Selection Systems

• All models feature combined knitting-transfer systems with split function, varying from 1×2 to 2×3 carriages depending on the model.
• Electronic wear-free selection systems with 2 selection points range from 6 to 16 units, enabling precise needle selection.
• Dynamic tension setting with step motors allows rapid stitch tension adjustments via Power Tension Setting (PTS).

2. Drive and Racking

• Main drive includes programmable speed, variable stroke, Power-RCR system (Rapid Carriage Return), and Carriage Force Control (CFC) for protection.
• Maximum knitting speeds vary between 1.0 m/s and 2.0 m/s depending on model and operation mode.
• Racking course is programmable up to 4 inches, with some models supporting additional beds for extended racking.

3. Needle Bed Specifications

• Nominal widths range from 24 inches (60 cm) to 96 inches (244 cm), with some tandem versions offering doubled widths.
• Gauge ranges vary widely, covering E 1.5.2 up to E 18, with gauge conversion possible within the same gauge range.
• Features include pelerine spring-transfer needles with spring-loaded latches, needle detectors, and optional needle exchange systems.
• Some models include moveable or spring-loaded holding-down jacks and knockover bits.

4. Yarn Handling and Control

• Yarn control units range from 10 to 36 depending on model and gauge.
• Active thread clamps are typically 8 per side, with lateral yarn tensioners and thread brakes equipped with scales for precise tension control.
• Yarn carrier rails and carriers vary, with some models supporting intarsia and plating yarn carriers, including plating kits with bobbin holders.
• Optional equipment includes devoré kits (single or double systems), plush devices, and holders for bobbins.
• Yarn feed units may include friction feed wheels and storage feed wheels; ASCON® automatic stitch control systems are available on select models for stitch length measurement and regulation.

5. Fabric Take-Down and Cleaning

• Main take-down systems use Stoll-multiflex® belts or double rollers, with some models featuring comb take-down and auxiliary take-down options.
• Cleaning devices include suction turbines with suction tubes on select models.

6. Dimensions and Weight

• Machine lengths range from approximately 1838 mm to 5100 mm unpacked, with corresponding increases when packed or palletized.
• Widths are generally around 909 mm to 1062 mm unpacked, with packing widths up to 1470 mm.
• Heights are consistent around 1800 mm to 2090 mm unpacked.
• Weights vary significantly, from approximately 736 kg net for smaller models to over 2060 kg net for larger units.

7. Control Systems and Safety

• All machines feature Slide Multi-Touch Panels with color displays (non-moveable) for user interface.
• Connectivity includes 2 USB ports and Ethernet for online operation.
• Battery backup ensures knitting process continuation after power failure.
• Safety features include fully enclosed working areas, compliance with EC regulations (CE label), and machine status lamps with alarm buzzers.

8. Power Requirements

• Voltage connections vary between AC 230V and AC 400V with ±10% tolerance depending on model.
• Power consumption ranges from approximately 1.7 kW to 3.0 kW depending on operating status and machine size.
• Actual power consumption during knitting depends on gauge and working conditions and is typically lower than the maximum connection value.

9. Additional Notes and Options

• All systems are fully independent, supporting three-way knitting techniques or simultaneous front and rear transfers.
• Gauge availability and conversion options are detailed, with some features dependent on gauge selection.
• Optional equipment availability includes devoré kits, plush devices, friction feed wheels, and ASCON® systems.
• Technical data is subject to change as products undergo continuous development.
