Two different approaches to roll splicing are used depending on production needs—manual systems that rely on operator control, and semi-automatic systems that improve consistency and speed.
Manual Splice Table: A manual splice table is used to connect the end of one material roll to the start of the next so production can continue without changing rolls. It provides operators with a flat, stable surface to align, join, and secure material before the line is restarted.
During a manual splice, operators position the outgoing material and the new roll on the table, align them by hand, and create a controlled overlap or seam. The materials are then bonded together using tape, adhesive, or heat‑activated methods, depending on the process. Once the splice is checked visually for quality, production resumes and the new roll feeds through the line.
Because all steps are performed manually, splice quality relies on operator experience and attention to detail rather than automated systems. Manual splice tables are simple, reliable, and easy to maintain, making them a practical solution for lower‑speed lines, shorter production runs, frequent changeovers, or as a backup to automated splicing equipment.
Semi-Automatic Splice Table: The semi‑automatic splice table is designed to join rolls of reinforcement material quickly and consistently during shingle production. It uses a hot‑melt glue film to create a strong, reliable splice that keeps material moving smoothly through the line.
Operators feed the reinforcement into the table, secure it in place, and trim it to length before the splicing press is activated. Heated upper and lower press beams apply controlled heat and pressure to bond the material together, ensuring a uniform splice every time.
Built‑in temperature and pressure settings help maintain repeatable results, while the press automatically moves away from the material when not in use. An integrated brake roll at the exit end holds the reinforcement steady during splicing and separates the process from the downstream accumulator to prevent unwanted movement.
This semi‑automatic design supports efficient roll changes while maintaining consistent material flow and splice quality.
