AI Technical Summary
Technical Problem
Existing yarn unwinders suffer from poor or jerky unwinding behavior, leading to knots and tangles, especially when used in manual crafts where both hands are occupied, due to rotational forces causing tilting and jamming under angled loads.
Method used
A device with a support element centrally connected to an axle, rotatably connected to a retaining element via a ball bearing swivel, ensuring symmetrical load distribution and smooth unwinding, even under transverse loads, using detachable connecting elements for easy assembly and disassembly.
Benefits of technology
Enables continuous, tension-free, and smooth unwinding of yarn, allowing uninterrupted manual work with both hands free, and is portable and reliable under various loads.

Abstract
The invention relates to a device (100, 101) for unwinding yarn, comprising a carrier element (1), a shaft (2) and a holding element (3), wherein the carrier element (1) is centrally connected to the underside (4) of the shaft (2) and the shaft (2) is rotatably connected, at its upper side (5), to the holding element (3). The aim of the invention is to enable continuous, tension-free and smooth unwinding of yarn. This is achieved in that a ball bearing swivel (6) is provided between the shaft (2) and the holding element (3).
