Sample warper

Abstract

#CMT# # / CMT# The sample warping machine (1) has a warping drum (2) that is connected with a winding drive (3). A yarn guide unit (6) is movably connected in parallel to the axis of the warping drum. Several attachment rods (9) are attached to the peripheral surface of the warping drum. A sensor arrangement (11) is arranged for detecting the positions of the attachment rods attached to the peripheral surface of the warping drum. The sensor arrangement is arranged opposite to the end surface of the warping drum. #CMT#USE : # / CMT# Sample warping machine used for producing pattern chain or short chain. #CMT#ADVANTAGE : # / CMT# The reliable operation of the sample warping machine can be ensured by detecting the positions of attachment rods that are attached to the peripheral surface of warping drum connected to winding drive. The end faces of the attachments rods released during warping are not covered by the wound threads. Hence the positions of rods can be recognized easily by the sensor arrangement. The sensor arrangement is arranged opposite to end surface of warping drum and is fixed in rotational direction of warping drum. Hence all positions of rods can be determined at low signal processing cost and effort. #CMT#DESCRIPTION OF DRAWINGS : # / CMT# The drawing shows a perspective view of the sample warping machine. 1 : Sample warping machine 2 : Warping drum 3 : Winding drive 6 : Yarn guide unit 9 : Attachment rod 11 : Sensor arrangement.

Description

technical field [0001] The invention relates to a fancy warping machine with a warping cylinder connected to a winding drive, at least one thread guide movable parallel to the axis of the warping cylinder and a Multiple distribution sticks. Background technique [0002] This type of fancy warping machine is used to produce what is called a sample warp or short warp. For this, the warping cylinders are rotated. The yarn guides (generally, several at the same time) either guide the yarn around the circumference of the warping cylinder, where they are generally unwound on a conveyor belt, or guide the yarn at the front end of the warping cylinder , at this point, they are unwound on the "core", that is to say, on an auxiliary transport device, if it is not necessary to form the warp yarns of the sample. [0003] During the production of warp threads, that is to say during the production of sample warp threads, it is generally necessary to form what is known as a warp parting...

Problems solved by technology

This can cause problems during restarting of the warping cylinders, since the threads can then no longer be placed correctly on the warp rods
