Compensating device for fluctuating conveying speeds of a fibrous nonwoven

摘要

A compensating device (1) for fluctuating transport speeds of a fiber nonwoven (3). The compensating device (1) has a buffer belt (2) driven in a loop with three or four or more deflection points (12, 13, 14, 15, 16) and with a variable sag (11) of the carrying run supporting the fiber nonwoven (3). The compensating device (1) further has an adjusting element (19) for adjusting the location of at least one deflecting point (15, 16).

1. A compensating device for fluctuating conveying speeds of a fibrous nonwoven, the compensating device comprising:
an endless circulating driven storage belt; a plurality of deflection points comprising two spaced apart fixed upper run deflection points defining a variable slack circulating driven belt upper run carrying the fibrous nonwoven, the plurality of deflection points further comprising two or more compensating deflection points defining taut belt runs between one of the compensating deflection points and one of the upper run deflection points, between another of the compensating deflection points and another of the upper run deflection points and between compensating deflection points; and an adjusting device shifting at least one of the compensating deflection points for moving one of the compensating deflection points to change a spacing between two of the compensating deflection points, to change an amount of belt comprised by the taut belt runs and to compensate the variable slack circulating driven belt upper run of the storage belt.
