Core yarn supplying device and spinning machine

Abstract

A core yarn supplying device and a spinning machine are provided. The core yarn supplying unit (51) includes a tension applying section (70) adapted to apply tension to a core yarn (C); a slack applying section (80) adapted to apply slack to the core yarn (C); a core yarn feeding unit (100) adapted to feed the core yarn (C) at downstream of the tension applying section (70) and the slack applying section (80) in a travelling direction of the core yarn (C); and a detecting section (90) adapted to detect status of the core yarn (C) at upstream of the tension applying section (70) in the travelling direction of the core yarn C.

Description

technical field [0001] The present invention relates to a core yarn supply device and a spinning machine. Background technique [0002] As a conventional core wire supply device, there is known a tension applying part that applies tension to the core wire, a slack applying part that applies slack to the core wire, a tension applying part in the traveling direction of the core wire, and a downstream side of the slack applying part. A core wire supply device of a core wire delivery unit that feeds out a core wire (for example, refer to Japanese Patent Application Laid-Open No. 2012-131591). Such a core wire supply device may include a detection unit that detects the state of the core wire (for example, the presence or absence of the core wire, etc.). [0003] However, in the aforementioned core wire supply device, depending on the type of the core wire, the state of the core wire may not be detected with high accuracy. Contents of the invention [0004] An object of the pr...
