Capabilities

The Winkler + Dünnebier 2741 is a specialized envelope manufacturing system designed for producing custom envelopes, photo pouches, and multi-fold mailers without gumming. It handles paper weights from 70–270 g/m², accommodates widths up to 620mm, and processes lengths between 150–470mm. The machine offers flexible folding capabilities with adjustable bottom flaps (25–45mm) and side flaps (up to 50mm), making it ideal for producing non-standard envelope formats.

Industries & Uses

This equipment serves print shops, direct mail companies, packaging producers, and corporate communication departments that need high-volume custom envelope production. It's particularly valuable for businesses handling specialized formats like padded photo mailers or complex multi-panel designs. The no-gumming capability means lower consumable costs and faster processing for dry-fold applications.

What to Check When Buying

When evaluating this 1979 model, request complete maintenance records and ask about wear on the folding mechanisms and paper guides—these components experience constant friction. Verify that all creasing and folding stations operate smoothly without binding. Check for consistent output quality by requesting production samples if possible. Confirm that all documentation is included, and arrange an on-site inspection to test run the machine with your target paper stock.
