Tape Layup Torque Transmission for Backing Material Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tape layup systems for composite component manufacturing are mechanically complex in collecting the backing material from tackifier tape, which hinders efficient application and bonding processes.
Innovation Solution
A tape layup system comprising a frame, a feed spool, an uptake spool, and a torque transmission system that generates tension in the tackifier tape to separate the backing material from the tackifier material at a compaction roller, automatically rotating the uptake spool to collect the backing material onto a separate roll, thereby simplifying the collection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a tackifier tape system is used to apply tackifier material, then the application process becomes fast and simple, but the mechanical complexity of collecting the backing material increases
Solution Approach 1:
The invention extracts and separates the backing material collection function from the main tape application system. By using a dedicated uptake spool that automatically winds the released backing material, the system removes the complex mechanical collection mechanisms from the application path, simplifying the overall device while maintaining high productivity
Solution Approach 2:
The uptake spool operates autonomously to collect and wind the backing material as it is released from the tackifier tape. This self-service mechanism eliminates the need for external collection systems or manual intervention, reducing mechanical complexity while preserving fast application speeds
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enables efficient and automatic separation and collection of backing material, reducing mechanical complexity and enhancing the application process by maintaining tension in the tackifier tape and ensuring consistent adhesion to the work surface.
Implementation Method 1
a torque transmission system configured to convey a torque from the feed spool to the uptake spool
Implementation Method 2
the tape layup system operates to generate a tension in the tackifier tape between the compaction roller and the feed spool to pull the tackifier tape from the tape roll
Implementation Method 3
applying a tackifier material to a work surface to hold a composite detail to the work surface

AI summary
Tape layup systems and associated methods. A tape layup system includes a feed spool and an uptake spool. The feed spool is configured to carry a tape roll of tackifier tape that includes a tackifier material and a backing material, and the uptake spool is configured to carry a backing material roll of the backing material. The tape layup system further includes a torque transmission system configured to convey a torque from the feed spool to the uptake spool. The tape layup system is configured such that conveying a torque from the feed spool to the uptake spool operates to draw the backing material onto the backing material roll. A method of operating a tape layup system includes generating tension in a tackifier tape to rotate a feed spool and consequently rotating an uptake spool to draw a backing material onto a backing material roll.
