Embodiment Construction

[0058] FIG. 1 shows a known card 1 in which the batt F is fed from a feed box 2 to a feed roller 3 and subsequently to a licker-in roller 4 . The card 1 comprises a single cylinder 5 (main cylinder or so-called tenter drum) which is rotatably mounted in a frame. The cylinder 5 operates in a known manner with a rotary flat device 6, a fiber feeding device 7 and a fiber doffing device 8, the fiber feeding device 7 particularly comprising a feed roller 3 and a licker-in roller 4, and the fiber doffing device 8 In particular the so-called Doffer 9 is included. Carding elements 10 can be installed in the pre-carding zone, post-carding zone and secondary carding zone of the card 1 . Between the revolving flat arrangement 6 and the carding element 10 is located a fiber guiding element, which is not shown in detail here and will be described in further detail below. The fiber doffing device 8 conveys the fiber sliver FB to the fiber sliver depositing device 11 .

Abstract

The present invention relates to a spinning preparation machine, such as e.g. a carding machine or a cleaner or the like. Said machine comprises a device for the contactless measurement and / or adjustment of parameters in two opposite card clothings (21, 25). The tips (22, 26) of said card clothings are configured so as to be electrically conducting, a voltage source (41; 101; 201, 206) is connected to the tips of at least one of the card clothings, and electrical discharges can be produced by applying a variable potential difference between the tips of the two card clothings. These discharges are indicative of the actual distance (d) and / or the distance to be adjusted between the card clothing tips and / or the degree of wear of at least one of the card clothings and / or the position of the one card clothing in relation to the other card clothing, especially the angle of inclination (T) relative each other. The invention also relates to a corresponding contactless measuring method.

Description

technical field [0001] The invention relates to a spinning preparation machine and a contactless measuring method according to the preambles of the independent claims. Background technique [0002] Various contactless measuring methods and corresponding devices are known for determining the distance between the top ends of card clothings. For example, DE 42 35 610 A1 discloses an inductive sensor which is assigned to a flat of a card and is arranged opposite a roller clothing. DE 102 51 574 A1 describes an optical sensor which detects the distance between the free end of a card clothing and a corresponding reference surface. DE 39 13 996 A1 likewise discloses sensors of the non-contact type, wherein the sensors are specified here as capacitive sensors, inductive sensors and optical sensors. [0003] The indirect measuring method is a method that does not measure the direct distance between opposing clothing tips. An example of this is described in the aforementioned DE 42...
