Embodiment Construction

[0024] The first area of ​​application of the device for the guided transport of the web according to the invention is the guidance of the web around the deflection rollers so that the web then has its top surface downwards. This variant is mainly used in crosslappers configured as horizontally staggered layers.

[0025] figure 1 A crosslapper of this type is shown with an output conveyor belt 3, the function of which is to convey the laid non-woven fabric in a conveying direction perpendicular to the plane of the drawing. The guide means of the output conveyor belt 3 comprise upper deflection rollers 5 . Above the output conveyor belt 3 , a laying carriage 7 can move back and forth on guide rails (not shown) transverse to the conveying direction of the output conveyor belt 4 . Two freely rotatable deflection rollers 9 and 11 are supported in the laying carriage 7 . The deflection roller 9 is partially surrounded by the first cover belt 13, which comprises a section extendi...

Abstract

A device for guided transport of a web (69), comprising: a web transport device (51) having an annular outer surface for transporting the web (69) in a transport direction (F), and a guide element ( 71, 71a-d), arranged to be opposite to and facing the outer surface of the outer surface of the web transport device (51) with a direction transverse to the conveying direction (F) A surface profile comprising an alternating plurality of protrusions (73, 73a-d) and depressions (75, 75a-d). The protrusions (73, 73a-d) and depressions (75, 75a-d) extend in the conveying direction (F) of the web (69). The protrusions (73, 73a-d) form guide surfaces for guiding the web (69) and the recesses (75, 75a-d) form ventilation grooves for guiding away the entrainment carried along with the web (69). Air. The guide elements (71, 71a-d) are concavely curved in the conveying direction (F) and the protrusions (73, 73a-d) are directed radially inwards.

Description

technical field [0001] The present invention relates to a device for the guided transport of card webs. Background technique [0002] The web for the production of non-woven fabrics is conveyed from the carding machine to a crosslapper, in which the web of material fibers is produced, in which several layers of Mesh cotton to form thicker non-woven fabrics. During the entire conveying distance of the web from the carding machine to the point at which the web is laid in the crosslapper, the problem arises that the conveyor belts of the web, due to their high speed, carry air with them. This air can cause air bubbles to form when the web is deflected around deflection rollers or when two conveyor belts are brought together. Air escapes sideways and jitters the belt and blows out the web. It can also cause mesh breakage and elongation or expansion of the mesh. In general, it can be said that this air causes inhomogeneities in the web. As the web is deflected around the def...
