TTR Slitter Rewinder

Description

A TTR Slitter Rewinder is a precision converting machine designed specifically for the Thermal Transfer Ribbon (TTR) industry. Its primary function is to unwind jumbo rolls of TTR film, slit them into multiple narrower widths using precise blade systems (typically razor or magnetic blades), and rewind them onto smaller cores (such as 1-inch or 1/2-inch) for use in barcode and label printers.

Features

• High-Precision Slitting – Uses magnetic blade holders or razor blades to achieve clean edges on thin films (typically 4–20 microns). Minimum slit widths can go down to 20–25 mm .
• Automatic Tension Control – Servo motors (often 4 independent units) and PLC control (e.g., Siemens) maintain consistent web tension from unwind to rewind, preventing stretching or wrinkling .
• Leader/Trailer Handling – Semi-automatic or fully automatic stations apply leader and trailer tape/film, reducing manual labor and material waste (ribbon-saving function) .
• Turret Rewinding (High-End) – Fully automatic models feature a turret system that switches finished rolls without stopping the machine, boosting throughput for large-volume production .
• Core Compatibility – Handles both 1-inch and 1/2-inch cores interchangeably, which is essential for serving different printer requirements .
• Speed Range – Varies by model: entry-level/compact units run at 30–80 m/min; mid-range at 250–300 m/min; fully automatic high-speed lines reach 400–450 m/min .
