Abstract: The installation includes two needling apparatuses (2, 3) which succeed each other on one side of the path (1) for the fleece to be needled. The needles (47) have an “elliptical” movement, i.e. their reciprocating movement of penetration is combined with a reciprocating movement parallel to the direction of progression. The two mechanisms are actuated at the same speed but with a phase shift of 180° between them. The installation is used for balancing horizontal vibrations.

Abstract: A needle loom (2) for the consolidation of a fleece is preceded in the same installation by a pre-needle loom (3) having an “elliptical” movement, i.e. the needles (47) of which have a component of movement in the direction (6) of the progression of the fleece of fibres when they are in penetration phase in the fleece. The component is used as an additional way of propulsion of the fleece into the entrance to the needle loom (2).

Abstract: The invention relates to a method for the protection of germinating seed from pesticide, wherein seed-containing pellets and pesticide-containing pellets are sown separately but simultaneously. According to a preferred embodiment of the invention, the pesticide-containing pellets have substantially the same shape and diameter as the seed-containg pellets, and the pesticide-containing pellets comprise the exact dosis of pesticide that is sufficient for one seed germ. Generally, the pellets with pesticide have a diameter ranging from 0,5–5.

Abstract: This invention relates to a saddle support device to compensate for the variations between the compound curved surfaces of animal backs and the corresponding compound curved surfaces of saddles. This invention includes a method of manufacturing that employs a measurement device with transverse linkages for defining the compound curved surface of the animal's back, that can have an additional adjustable form jig mechanism attached to create a fair curve between the transverse linkages, so that a moldable plastic can be draped over the adjustable form jig, to create a compound curved saddle support device. Employing the preferred method of manufacturing, a semi-rigid saddle support device comprising a two distinct panel structure with a single alignment arch can be made that will fit over the animal's back, to protect the loaded animal from the higher pressures caused by the variations in the saddle construction.

Abstract: A method is provided for controlling hydraulic flow to a hydraulic actuator. The method includes generating a command signal based on an operator input, sensing a linkage position associated with the hydraulic actuator, and selecting a moving rate of a valve associated with the hydraulic actuator based on the sensed linkage position and the command signal. The valve is modulated to control the hydraulic flow to the hydraulic actuator based on the selected moving rate.

Abstract: An installation includes a carding machine (1), and a distributor-layer (2) depositing the card (1) web (6) in a reciprocating motion on a delivery belt (8) moving transversely. The resulting intermediate lap (16) is conveyed to a needling loom (3) to produce a consolidated lap (24). A measuring station (28) scans the consolidated lap (24) profile and transmits it to a processing unit (32) where the profile is compared to a set reference input by a terminal (33). The variations in width cause a corresponding modification in the width deposited by the distributor-layer (2) by a link (36). The local surface weight variations cause a corresponding modification of the controls applied to the carding machine (1) capable of longitudinally profiling the web (6). The invention is useful for controlling an installation for obtaining a finished product.

Measuring means are provided in the machine located in the needling head to measure the position of the top surface of the textile structure at the low point of maximum penetration of the needles. The measuring means are preferably disposed in a midplane of the needling head perpendicular to an advance direction of the textile structure.
