Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for mechanically manufacturing filling material products from paper webs face issues with high-speed conveyor jams, leading to operational interruptions and increased maintenance needs, due to the risk of manual intervention and complex safety measures.
Innovation Solution
A device that includes a cutting-to-length mechanism followed by a removal device to transport the separated filling material product away immediately, preventing collisions and jams, and allowing for increased delivery speeds with reduced maintenance requirements, while ensuring safety through the arrangement of components in the conveying flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the conveying speed of filling material products is increased to improve productivity, then the production efficiency is improved, but the risk of conveying jams increases due to collisions between separated products and the trailing strand
Solution Approach 1:
The patent extracts the separated filling material product from the trailing strand immediately after cutting by using a removal device that actively transports the cut product away from the cutting zone. This prevents the separated product from colliding with the trailing strand, thereby eliminating the conveying jam risk while maintaining high conveying speeds.
2Object-affected harmful factors
If additional safety features such as protective flaps are added to prevent manual intervention through the discharge opening, then the safety is improved, but the device complexity and acquisition costs increase
Solution Approach 1:
The removal device automatically transports the separated filling material product away from the cutting zone at high speed, creating a self-protecting system where the rapid movement of materials itself prevents access to the cutting area. The system uses its own operational characteristics (high-speed conveying) to provide safety without additional protective structures.
3Object-affected harmful factors
If additional safety features and protective flaps are incorporated to meet safety requirements, then the safety is improved, but the maintenance complexity and time required to clear conveying blockages increase
Solution Approach 1:
By extracting the separated product immediately from the cutting zone using the removal device, the patent eliminates conveying jams before they can occur. This prevents blockages that would require manual intervention, thereby reducing maintenance time and complexity while maintaining safety through the inherent design rather than additional protective elements.

AI summary
The invention relates to a device for the machine-production of a packing material product consisting of a single-ply or multi-ply continuous paper web, said device comprising a feed system for drawing the paper web into the device, thus defining a conveying direction, and a cutting device for detaching the packing material product from a run of three-dimensional packing material formed in the device from the paper web. According to the invention, a transport device adjoins the cutting device in the conveying direction, said transport device transporting the detached packing material product away from the cutting device.
