Wire Binding Machine with Folding and Twisting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing binding machines pose a safety risk to operators due to protruding wire tips after binding, and they lack efficiency in securing bundles or skeins effectively.
Innovation Solution
A binding machine that folds the wire terminal portions into eyelets before twisting, using a wire-guide with multiple channels for two turns around the object, feeding and retracting mechanisms, cutting, folding, and twisting devices to secure the wire safely and tightly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the wire terminal portions are twisted directly after cutting, then the binding process is simple and fast, but the protruding tips pose a safety risk to operators
Solution Approach 1:
The wire terminal portions are folded into eyelets before the twisting operation. This preliminary folding action eliminates the protruding sharp tips that cause safety hazards, while still allowing the subsequent twisting to secure the binding efficiently. The eyelet formation prepares the wire ends in a safe configuration prior to the final twisting step.
2Productivity
If the wire is wound with only one turn around the object, then the binding process is faster and simpler, but the binding security and tightness are insufficient
Solution Approach 1:
The wire-guide is divided into multiple channels (at least two) that guide the wire to make multiple turns around the object. This segmentation of the wire path ensures the wire wraps around the object at least twice, providing superior binding security and tightness while maintaining an automated efficient process through the structured multi-channel guide.

AI summary
A binding machine (1) adapted to bind an object, such as a bundle or a skein, comprises a wire-guide (5) adapted to guide a wire around a space (S) where the object to be bound is housed, the wire-guide (5) comprising at least two channels (5', 5") to perform at least two turns of the wire around this space (S), feeding means (3) adapted to feed the wire to the wire-guide (5) and to retract the wire in order to tighten it around the object to be bound, as well as cutting means (7) of the wire adapted to separate from this wire a segment thereof, this segment being tightened around the object and comprising two free terminal portions. Conveniently, the binding machine (1) comprises folding means (8a, 8b) adapted to fold the terminal portions of the wire segment so as to form an eyelet (E), and a twisting device (4) adapted to twist these eyelet-shaped terminal portions.
