Abstract:
A bale opener for removing fiber tufts from top surfaces of fiber bales assembled in a series includes a carriage for travelling back-and-forth along a generally horizontal, first path of travel along the fiber bale series; a tower mounted on the carriage for travel therewith; a fiber tuft detaching device extending from the tower and movable relative to the tower along a generally vertical, second path of travel; and an incremental rotary displacement signalling device including a shaft; a toothed rotary element mounted on the shaft; a counter element meshing with the rotary element which is movable relative to the counter element; and a signal generator coupled to the toothed element for generating signals as a function of rotary displacements of the toothed element. One of the elements is mounted on the detaching device (or other co-travelling component) and the other element is mounted along one of the first and second paths of travel for generating signals as a function of displacement of the detaching device along at least one of the first and second paths of travel.
Abstract:
An apparatus for placing fiber bales into readiness for removing fiber tufts therefrom by a travelling bale opener has a fiber bale depositing device for positioning an initial fiber bale at an inclined orientation to the vertical and for positioning, adjacent the initial fiber bale, an additional fiber bale at an angle of inclination greater than the angle of inclination of the initial bale as viewed codirectionally with the angle of the initial bale; a bale-supporting device for engaging and stabilizing the initial fiber bale; a displacing device for moving the bale-supporting device into and out of engagement with the initial fiber bale; and a control device for automatically operating the fiber bale depositing device and the displacing device for automatically and sequentially depositing the initial fiber bale, moving the bale-supporting device into engagement with the initial fiber bale, depositing the additional fiber bale into a countersupporting engagement with the initial fiber bale and moving the bale-supporting device out of engagement with the initial fiber bale.
Abstract:
A fiber feeder apparatus includes a driven endless supply conveyor belt having a coneveying surface for supporting a fiber pile and an endless spiked lattice arranged at one end of the supply conveyor belt and extending at an upward inclination therefrom. The spiked lattice has spikes arranged to penetrate into the fiber pile for effecting removal of fibers from the fiber pile. The supply conveyor belt is driven such that the fiber pile is being fed by the conveying surface into contact with the spikes. There is further provided a control device which is connected to the drive of the supply conveyor belt for effecting a nonuniform driving thereof.
Abstract:
An apparatus for measuring the thickness of a plurality of side-by-side running slivers includes a supporting surface guiding the side-by-side running slivers thereon in a single plane; a holding member; and a plurality of sensor elements movably secured to the holding member to be movable in a direction transverse to the plane. Each sliver is contacted by a separate sensor element for causing excursions thereof by thickness fluctuations of the running sliver. Each sensor element is yieldingly pressed against a respective sliver, and each sensor element cooperates with the supporting surface for pressing the running slivers against the supporting surface. An adding device adds the excursions of the sensor elements, and a transducer converts the excursion values into electric pulses.
Abstract:
A fiber bale opener includes a downwardly open housing which is adapted to be supported above fiber bales to be opened and which accommodates an opening roller having an axis and being arranged for detaching fiber tufts from upper bale surfaces. In the housing there is further arranged a suction duct through which fiber tufts detached by the opening roller are adapted to be removed by a suction air stream flowing therethrough. The suction duct has two lateral walls which are facing one another and which are spaced from one another in a direction parallel to the roller axis. One lateral wall has an upwardly extending first oblique air guiding face and the other lateral wall has an upwardly extending second oblique air guiding face. The first air guiding face projects into the suction duct to a maximum extent of between one fourth and one third of a width dimension of the suction duct measured parallel to the roller axis at a location adjacent the opening roller and further, the second air guiding face has a bent portion for changing an upward inclination thereof.
Abstract:
An apparatus for placing fiber bales end-to-end in a series includes a bale emplacement for supporting thereon the bales forming the series; a bale depositing device for setting a fiber bale at an inclination on the bale emplacement to build the series; and a bale holding device situated at a location along the bale emplacement. The bale holding device has a bale engaging member movable into engagement with a vertical lateral face of a bale situated at the location for stabilizing the bale; and a power device for moving the bale engaging member into or out of engagement with the bale situated at the location.
Abstract:
An apparatus for placing fiber bales in readiness for removing fiber tufts therefrom by a travelling bale opener having an operational range, includes a first arrangement for supporting thereon a plurality of consecutively positioned fiber bales forming a standby bale series having a leading end and a trailing end; and a second arrangement for supporting thereon a plurality of consecutively positioned fiber bales forming an operational bale series to be worked on by the bale opener. The trailing end of the standby bale series is at a greater distance from the second arrangement than the leading end. The second arrangement receives fiber bales from the first arrangement for replenishing the fiber bales of the operational bale series with fiber bales of the standby bale series. The apparatus further includes a bale transporting carriage for conveying a fiber bale to the trailing end of the standby bale series and for depositing the fiber bale, conveyed by the carriage, onto the first arrangement at the trailing end to replenish the standby bale series.

Abstract:
An apparatus for treating a fiber bale having a soiled surface. The apparatus includes a cleaning device arranged for engaging a bale surface to remove soiled material therefrom and a displacing arrangement for effecting a relative motion between the fiber bale and the cleaning device.
Abstract:
A bale opener arranged for travel along a series of fiber bales for removing fiber tufts from top surfaces thereof. The bale opener includes a toothed opening roll supported in an orientation transverse to a direction of travel and a grate formed of grate bars spaced in a direction transverse to the direction of travel and arranged for engaging the top surfaces of the fiber bales. The teeth of the opening roll extend between the grate bars for penetrating into the fiber bales during travel. There are further provided bale pressing elements supported by the bale opener on opposite sides of the opening roll spaced therefrom parallel to the direction of travel. The bale pressing elements are arranged to engage and press down the fiber bales during travel of the bale opener. A setting arrangement simultaneously vertically adjusts the bale pressing elements in opposite directions.
