Two common methods of roll splicing are used based on production requirements: manual systems that depend on operator involvement and semi-automatic systems that enhance repeatability and efficiency.
Manual Splice Table:
A manual splice table is used to connect the end of one material roll to the beginning of the next, allowing production to continue during roll changeovers. It provides operators with a stable work surface for properly aligning and joining the material before the line is restarted.
To perform a splice, the outgoing material and incoming roll are positioned on the table and aligned manually. Operators then create the splice by overlapping the material and securing it with tape, adhesive, or heat-activated bonding methods, depending on the application. Once the splice has been inspected and verified, the line can resume operation with the new roll feeding into production.
Because the process relies entirely on manual operation, splice quality is influenced by the skill and attention of the operator rather than automated controls. Manual splice tables are simple, reliable, and easy to maintain, making them well suited for lower-speed operations and shorter production runs.
Semi-Automatic Splice Table:
A semi-automatic splice table is designed to produce fast, repeatable splices while maintaining consistent material flow during shingle manufacturing. The system uses a hot melt glue film to create a durable bond between rolls of reinforcement material.
During the splicing process, operators position the reinforcement material within the table, secure it in place, and trim it to the required length. Once initiated, heated upper and lower press beams apply controlled temperature and pressure to form a consistent splice across the material.
Built-in temperature and pressure controls help deliver uniform results from splice to splice, while the press automatically retracts when the cycle is complete. A brake roll located at the discharge end of the table stabilizes the reinforcement during the splice and isolates it from the downstream accumulator, helping prevent unwanted material movement.
By combining operator input with automated pressing functions, the semi-automatic splice table supports efficient roll changes, reliable splice quality, and uninterrupted material handling throughout the production process.
