An Envelope Window Pasting Machine automatically applies clear film (windows) onto envelopes or cartons, featuring high-speed, precise operation with feeders, gluing, and patching units, using cold glue for applications on gift boxes, CD sleeves, and standard envelopes, ensuring uniform application and efficient production.
Key Features & Components
Automatic Feeding: Pulls paper from a stack, often using suction or belts, for non-stop, smooth operation, preventing missing or overlapping sheets.
Precise Positioning: Uses advanced mechanisms (like chain dialing pins) to accurately position materials for exact window placement.
Gluing System: Applies a consistent, uniform layer of cold glue via cylinders or sprayers.
Patching Unit: Automatically cuts and pastes the film (often plastic/cellophane) over the window area.
Delivery System: Collects finished products, often with digital counters for tracking.
Applications & Benefits
Versatile: Used for various products, including gift boxes, toy boxes, DVD envelopes, and standard mail envelopes.
High Efficiency: Achieves high speeds (thousands of pieces per hour) with reduced labor.
Quality & Consistency: Ensures even glue application and accurate placement, leading to professional-looking finished products.
Technical Aspects
Materials: Built with durable materials like steel, often with imported components for stability.
Control: Features include digital counters and adjustable settings for different paper weights (gsm) and film thicknesses.
