Problems solved by technology
[0004] However, it is well known that if there is an increase in the number of carding cycles and thus if an increase in the conveying speed of the web occurs, a disordered edge region of the web may appear above the web guide
In this case, wear in the edge area may occur, which may cause problems in the area of transfer to the subsequent delivery roller

Embodiment Construction
[0023] Figure 1 shows a schematic vertical section through a section of a carding head of a carding machine. Carding machines generally have eight carding heads arranged next to each other.
[0024] According to FIG. 1 , the carding head comprises two pairs of separating rollers 1 , 2 and 3 , 4 and a pair of delivery rollers 5 , 6 . The separating rollers 1, 2, 3 and 4 and the delivery rollers 5, 6 are mounted rotatably about a horizontal axis within a frame 7 of the card, which is only schematically indicated. A web guiding device with a web guide 9 is mounted between the pair of separating rollers 3, 4 and the pair of delivery rollers 5, 6 by means of schematically illustrated fastening elements 14, which web guide For supporting a card web V (in short, referred to as web or web), which is transferred from the pair of separating rollers 3, 4 and proceeds to the pair of delivery rollers 5, 6.
[0025] The portion 9.1 of the web guide 9 directly adjacent to the pair of sepa...

Abstract
The invention relates to a netlike object leading device of a carding machine, which is provided between a pair of separating rollers (3, 4) and a pair of delivering rollers and used for supporting a netlike object guide plate (9) of a netlike object (V); the netlike object guide plate (9) is provided with lateral guide walls (15) at both longitudinal sides (LS), the netlike object guide plate (9) is respectively extended at an angle corresponding to a transmission direction of the netlike object in a longitudinal part (LA) of the pair of delivering rollers (5, 6) wherein the netlike object guide plate (9) is ended up, distance between guide walls (15) in the longitudinal part is continuously diminished. The invention also provides that: the guide walls (15) are respectively extended at an angle (alpha) ranging from 10 degrees or 30 degrees corresponding to the transmission direction (FR) of the netlike object guide (V) in the longitudinal part (LA), leading elements (17) are respectively provided within the areas of end parts (E) which are directly provided in front of the pair of delivering rollers (5, 6), the leading elements (17) protrude above the netlike object guide plate (9) and has a distance (a) from the netlike object guide plate.
Description
technical field [0001] The invention relates to a web guiding device for a carding machine. Background technique [0002] Conventional cards known today comprise separating rollers (usually two pairs) which are mounted in a frame and which are reciprocally rotated in a pilgrim-like motion when the card is in operation. Separation rollers form the carded fiber bundle into a card web, which is continuously supplied, and the separation roller transfers the card web to a web guide plate, which guides the web Leads to a pair of exit rollers that are also mounted in the frame. [0003] A web guide of this type has been shown and described, for example, in the publications DE4445150A1 and EP558442A1. In the version shown here, the guide plate is provided with side guide surfaces which serve as lateral guides for the web. Furthermore, it is known from these versions that the web guide comprises at least two differently oriented portions. In this case, the version of DE4445150A1 ...
