Abstract (en)
[origin: WO2011006761A1] The invention relates to a bottom holder for winding up a thread, wherein a bobbin case (2) can be slid onto a protruding bobbin spindle (1). In order to catch and clamp a thread on the circumference of the bobbin spindle (1) at the beginning of a bobbin travel, a thread catching device (16) and a thread clamping means (7) are provided at a free insertion end of the bobbin spindle. In order to both securely clamp and automatically release the thread end when sliding off a bobbin, according to the invention, the clamping means is formed by a hollow cylindrical clamping bushing (9), an outer cone (11) thereof being fitted into an inner diameter bounded by catches (8), such that a clamping slit (12) substantially axially oriented and open toward the insertion end (10) of the bobbin spindle is formed between the clamping bushing and the catch (8).
