Abstract: A loom, especially a loom equipped with a Jacquard mechanism is supported by a vibration isolating device. At least one, preferably two or four such devices are arranged in positions most effective for the vibration damping, with due regard to the center of gravity of the wrap beam and/or of the entire loom. At least one, preferably all vibration dampers are constructed to include a controllable level controlling element in the form of an air spring. The compression in the air spring is controlled in response to the spacing of a fixed point of the loom from the loom supporting surface. Thus, spacing variations between the loom and the Jacquard mechanism that could otherwise be caused due to weight changes of the loom, are eliminated or compensated, whereby the loom-Jacquard spacing is maintained constant.

Abstract: Vibrations of heavy equipment, such as textile machinery, are isolated, that is prevented from entering into the supporting floor, by inserting a vibration isolating device between each equipment frame member forming a machine foot and the floor. The device includes a hydraulic damper and up to three sets of springs, preferably sets of concentrically arranged helical springs. The springs are mounted between upper and lower spring mounting elements. The spacing between these upper and lower mounting elements is adjustable by a threaded bolt for adapting the load bearing capacity of each set of springs to the respective machine foot load. Thus, individual springs in a set or an entire spring set may be withdrawn from a load bearing function for providing each machine foot, for example of a weaving machine, with the individually required vibration insulation at each machine foot.
