Interfering edges are protrusions, edges, or uneven surfaces on components or in the screwdriving environment that can hinder the automated screwdriving process. They may block access to the screwdriving location to some extent. This also includes protective masks used to safeguard components. As a result, not every screwdriver can reach the screw point, which is why special technologies are required.
Interfering edges can appear in various forms—perhaps only on one side of the screw location, or possibly all around it. The depth of the screwdriving location affected by the interfering edge may also vary. Nevertheless, WEBER always finds the right solution for your application.
The following parameters are generally relevant for WEBER:
There is no interfering edge if, from P,
r > 20 mm und h < 30 mm
are maintained.

Mouthpiece solution for reduced accessibility to the screwdriving location
WEBER has developed targeted solutions to ensure reliable screwdriving even under challenging conditions. These solutions enhance process reliability and efficiency in screw assembly and enable dependable automation even with complex workpieces. The height and distance of the interfering edge are key criteria when selecting a suitable mouthpiece. The term “mouthpiece” refers to the frontmost part of a screwdriving spindle, where the fastener is held back after the feeding process until the screwdriving or setting operation begins.
These systems are specially designed for screwdriving tasks with axial feeding. Their robust design and precise screw feeding ensure high process stability, even when components feature interfering edges or uneven surfaces.
Thanks to its integrated vacuum screwdriving technology, this system enables precise screw feeding—even with difficult-to-access or irregular component geometries. Secure fixation of the screw at the tool head ensures accurate placement even in challenging environments.
This further development of the SEV system was designed specifically for applications with increased accessibility requirements. Its sliding design and optimized screw feeding allow even more flexible integration into automated processes.
Nora Erdei has been working as a product manager at WEBER Schraubautomaten GmbH for 2 years. She specializes in the product range of screwdriving spindles and the digitalization of screwdriving curve analysis. After studying Industrial Design Engineering, she designed the spindles she is now responsible for. Thanks to her Master of Science degree in industrial engineering, she also has the necessary know-how to successfully combine technical and economic aspects.
WEBER Schraubautomaten GmbH is a family-run and innovative company that attaches great importance to the sustainable design of the value chain. The result is high-quality products with maximum process reliability that make production processes more efficient. Your success is our success.
