Embodiment Construction

[0201] figure 1A known card 1 is shown in which batt F is conveyed from a feed box 2 to a feed roller 3 and thereafter a licker-in roller 4 . The card 1 comprises a single cylinder 5 (like a main cylinder or a so-called tenter drum) rotatably supported in a frame. The cylinder 5 works in a known manner with a revolving flat device 6, a fiber feeding system 7, in particular comprising a feed roller 3 and a licker-in roller 4, and a fiber doffing system 8, which in particular has a so-called doffer 9 . The carding elements 10 can be arranged in the pre-carding zone, post-carding zone and secondary carding zone of the card 1 . Between the revolving flat device 6 and the carding element 10 there is arranged a fiber guide element, which is not shown here in detail and will be explained in more detail below. The fiber doffing system 8 conveys the sliver FB to a sliver depositing device 11 shown schematically in the figure.

Abstract

The invention concerns a textile machine, in particular a spinning-preparatory machine, a device and a process for contactless measurement and / or adjustment of parameters between mutually opposite strips of card clothing (21, 25). The device comprises inter alia a voltage source (23) and a pulse generator (23a) for generating an alterable potential difference. The tips (22, 26) of the strips of card clothing (21, 25) are electrically conducting, and the pulse generator (23a) is connected to tips (22, 26) such that applying the alterable potential difference between tips (22, 26) of the two strips of card clothing (21, 25) makes it possible to generate at least two successive spark discharges. Means are provided for measuring the time between two spark discharges and / or a frequency measurement (28) for determining the current distance (d) between the card clothing tips (22, 26).

Description

technical field [0001] The invention relates to a device on a textile machine, in particular a spinning preparation machine, and to a contactless measuring method. The measuring method is used to measure the distance between two mutually facing components by means of a spark discharge. In use of the spinning preparation machine, the distance between two card clothings facing each other is measured and the risk of collision between them is also checked. Background technique [0002] Various devices have been disclosed which use the spark discharge principle to determine geometric quantities. Thus, for example, DE 3513799 C1 discloses a device for the contactless determination of distances by means of spark discharges in the field of manufacturing technology and robotics. In this case, a gas discharge is generated between the measuring electrode and the opposing workpiece by means of a high-voltage generator, which burns as a glow discharge. The gas discharge is maintained ...
