Splicing roll ends with impulse sealing
In conventional production facilities, manual splicing can lead to production interruptions and increased time expenditure, which reduces efficiency. It is also prone to errors, which can affect quality and result in higher labor costs due to the amount of work required. In addition, there is an increased risk of accidents for employees and the quality of the results can vary.
Increase productivity with partial automation or automation of the reel change. This minimizes machine downtimes and the production flow can be maintained continuously. At the same time, costs are reduced as less manual intervention is required, which increases efficiency. Automation gives you consistent sealing results and reduces the susceptibility of the work step to errors caused by manual intervention. Furthermore, workplace safety is improved and production flexibility is increased thanks to quick adjustments to different materials and packaging sizes.

Discover successful customer projects and practical application examples of our technologies in our case studies.
Splicing fleece fabric with impulse sealing
Customer requirement:
- Increase efficiency and safety of the roll change of a fleece fabric
- Enable a reliable and fast roll change without having to stop the machine. As the further transport takes place via turning rollers, the seam must not be too wide and tight, as this could cause problems during material transport.
ROPEX solution:
- A RESISTRON tool with a narrow heating tape and a matching backing with a flat silicone profile.
- Thanks to the rapid heating and cooling of the tools and the low heat input, the sealed seam is immediately resilient and stable for further processing in the machine.
- Reduction of unscheduled faults and a homogeneous seam surface over the entire length and ensures that the roll change is efficient, timesaving and resource-saving.
Customer benefits:
- Product safety: As there is no need to search for a broken needle in the fleece.
- Time saving: Compared to conventional sewing techniques, especially when joining two rolls with a web width of two meters, impulse sealing offers a significantly faster process.
- Reproducible sealing results: Ensuring consistent heat input with every cycle, resulting in reproducible seam quality.
- Homogeneous temperature distribution: The uniform temperature distribution on the heat-sealing band surface of our tools results in consistent seam quality over the entire seam length.
- Rapid heating: RESISTRON technology enables the sealing tool to heat up quickly, making the tools ready for immediate use.
- Rapid cooling of the tool: The tool cools down within a few seconds, resulting in short waiting times in the event of repairs. This reduces machine downtime and minimizes the risk of injury to personnel.
- Low energy consumption: Energy consumption is low as the sealing tool is only heated during the sealing process. This leads to an efficient and resource-saving use of energy.
Splicing changeover
Customer requirement:
- Customer wants to validate this process and wants to convert the reel change process from a manual to a semi-automated process.
ROPEX solution:
- Developed a suitable RESISTRON sealing tool that was optimized for the process parameters, such as material, pressure and time, in order to produce a repeatable sealed seam.
- Users make settings directly on the display control of the temperature controller. The tools then automatically seal the two roll ends together so that production of the medical bags can continue without interrupting the material.
Customer benefits:
- Consistent quality: fulfillment of the repeatability of the sealing process through partial automation for satisfactory sealing results.
- Technical support: Before, during and after implementation, the application engineers are on hand to provide technical advice and support during implementation.
- Flexible use: If the process parameters are changed, the tools and settings on the temperature controller can be easily adjusted.
- Energy efficiency: energy-saving technology ensures, it only consumes electricity during use.
