Problems solved by technology

What is unsatisfactory about this device is that there must be a parting warp, which will be inserted into or withdrawn from the warp yarn layer very laboriously

Embodiment Construction

[0021] Fig. 1 shows a layer 1 of warp yarns, which has a plurality of yarns 2 of essentially the same length and extending parallel to one another, said yarns being clamped at both ends 3, 4 respectively in a suitable clamping device not shown tight. The continuous yarns 2 are ideally spaced at the same distance from one another, but they can also be spaced differently without affecting the functionality of the invention. Therefore, these yarns 2 all lie in one plane, the plane of the warp layer. Warp yarn layer 1 does not contain warp dividing elements.

[0022] Fig. 1 also shows a video camera 5 placed above the warp layer plane and a light source 6 (such as a light emitting diode) below the warp layer plane, which all belong to an optical detection device. The camera 5 and the light source 6 are on the same optical axis 7, which is at least substantially perpendicular to the plane of the warp layer.

[0023] A suction device 8 is arranged between the camera 5 and the lig...

Abstract

The invention relates to a device for separating threads out of a fixed thread layer, whereby this device enables at least one thread to be separated out from the thread layer by using a separating means. The device comprises a suction means with which a negative pressure can be generated and comprises a drive means with which the suction means can be relatively displaced with regard to the thread layer. At least one thread is displaced in the direction of the suction means and the thread is separated out when the suction means approaches the thread layer and subjects the thread to a negative pressure.

Description

technical field [0001] The present invention relates to a device for separating quantitative yarns from a layer of warp yarns, wherein the yarns of the layer of warp yarns are tensioned at least in two positions, and a yarn can be separated from the layer of warp yarns by means of a separating mechanism. The invention also relates to a method according to the preamble of claim 13 . Background technique [0002] For example, the separation or separation of the yarns is an operation which must be carried out, for example, in order to draw the warp yarns into the heddles of a weaving machine. In this case, the warp threads are stretched in a frame where they together form a warp thread layer. Also, some of the yarns are very close to each other. Before being threaded, they should be separated from the warp layer, ie they must be separated from each other. In this case, the purpose of separating the yarns is to prepare a metered yarn, and in particular a yarn, for subsequent ...
