Embodiment Construction

[0021] figure 1 A card is shown, for example a Trützschler flat card TC, with a feed roller 1, a feed table 2, licker-in rollers 3a, 3b, 3c, a cylinder 4, a doffer 5, a stripper Take-off roller 6, clamping rollers 7, 8, web guide elements 9, bar funnel 10, delivery rollers 11, 12, rotary card top 13 with card top guide rollers 13a, 13b, cover plate 14, can 15 and Coil 16. The direction of rotation of the rollers is indicated by the curved arrows. Reference sign M 1 Indicates the center point (axis) of the cylinder 4, reference sign M 2 Indicates the center point of the doffer 5, while the reference sign M 3 Represents the center point of stripping roller 6. Reference numeral 4a designates the card clothing, while reference numeral 4b designates the direction of rotation of the cylinder 4 . Reference numeral 5a designates the card clothing, while reference numeral 5b designates the direction of rotation of the doffer 5 . Reference sign B indicates the direction of travel...

Abstract

The invention provides an apparatus at a flat card or roller card having a clothed cylinder and at least one adjacent clothed doffer. In an apparatus at a card having a clothed cylinder, clothed doffer 19a and a stripper roller 6, which co-operate with one another at a work spacing, a side screen 18a is arranged at both ends of the cylinder and immovably mounted on a frame 24. A displacement device 21a is provided for the doffer in order to set a predetermined work spacing using a setting device. In order to keep substantially constant, in use, the working gap between, on the one hand, doffer and cylinder and, on the other hand, doffer and stripper roller, the side part 18a is coupled to the holding element 19a for the doffer by at least one force transport device 21a, and mechanical means 28 are associated with a holding device for the stripper roller, by which means the work spacing between the doffer and the stripper roller can be set.

Description

technical field [0001] The invention relates to a device on a flat card or a roller card with a clothing cylinder, at least one adjacent clothing doffer and stripping rollers, which cooperate with each other and are in the form of a cylinder at the fiber transfer position The surfaces have a small mutual spacing (working spacing); the device has side parts (side screens) arranged at both ends of the cylinder and fixedly mounted on the frame; and has a displacement for the doffer The device uses the setting device to set a predetermined working distance. Background technique [0002] In modern high-performance cards, the heating of the components and the associated changes in the component spacing are becoming more and more important factors, and the same is true for the spacing between cylinder and doffer. In order to obtain good quality at maximum throughput, this spacing must be kept as constant as possible. However, the continued increase in production in the new genera...
