Abstract

The thread-tension meter has a housing (1) which is divided into a reading head (2) and a remaining housing part (3). The reading head (2) can be pivoted 90° relative to the remaining housing part (3), as required, so that it is possible to read off the thread tension easily in any position of the thread.

Claims

1. A thread-tension meter comprising

a housing consisting of a main portion and an end portion,

a device projecting from the main portion of the housing and intended for sensing the thread tension,

mechanical and electronic equipment, cables and accessories arranged within the housing for measuring the thread tension, and

an indicator device located in the end portion of the housing for reading off the measured value,

wherein the end portion of the housing in which the indicator device is located is self-contained,

wherein the end portion is pivotable at least 45°

relative to the main housing portion,

wherein a bushing extends through the end wall of the end portion of the housing and the adjacent end wall of the main housing portion and serves as a pivot bearing and cable duct,

wherein the end wall of the end portion of the housing adjacent the main housing portion is pressed by means of spring pressure against the adjacent end wall of the main housing portion, and

wherein an annular tensioning spring on the periphery of the bushing is adjustable by means of a nut screwed onto the bushing.

2. A thread-tension meter as claimed in claim 1 wherein one of the two end faces has a groove in the form of an arc of a circle and is coaxial relative to the axis of rotation of said housing end portion and into which projects a bolt fastened to or formed on the other end face in order thereby to limit the rotation of said end portion relative to the main housing portion to a desired angle, preferably 90°
