NT35 Inner Tape Applicator Head: Specialized Inner Side Taping for Corrugated Carton Stitching Lines

Corrugated carton stitching manufacturers suffer sharp staple edge damage to internal goods during transportation, while manual inner tape pasting after stitching brings low efficiency and uneven coverage. Keqi NT35 inner tape applicator head is custom-developed for inner-side tape attachment on single/double-piece corrugated cartons, perfectly matching automatic stitching machines, carton turners and independent offline gluing platforms.

Its core functional advantage lies in targeted protection of packaged products: after applying transparent or kraft tape on carton inner flaps, sharp metal staples are fully covered to prevent scratching electronic components, food goods and cosmetic items inside boxes, greatly improving product safety during logistics and storage. The modular structure supports seamless inline integration at the rear end of stitching equipment without disrupting original production workflow, and can also form a standalone taping platform for semi-automatic stitching machine matching.

NT35 adapts tape width of 20–35mm, processes carton flaps minimum 200mm wide, and runs at adjustable speed from 5–70 m/min to fit low and medium-speed corrugated production lines. It accepts tape rolls with inner diameter 76mm and maximum outer diameter 200mm, with taping accuracy controlled at ±3mm to ensure complete staple coverage without tape offset. The whole unit adopts wear-resistant transmission components to resist heavy corrugated board impact under long-hour continuous operation.

Primary applications cover express logistics corrugated boxes, home appliance outer packaging, fruit transport cartons and industrial component shipping boxes. Carton factories installing NT35 cut manual inner taping labor costs drastically, standardize inner packaging appearance and strengthen brand competitiveness with neat, uniform inner tape layout. Customized wider tape frames and dual-head synchronous taping structures are available for large-volume corrugated box mass production orders.
