An apparatus for severing ties or a wrapper surrounding a fiber bale includes a severing device having a cutting element and a drive for actuating the cutting element; a counterelement positioned adjacent the cutting device; a supporting device for positioning the fiber bale; and a displacing device for moving the severing device and the cutting device as a unit relative to the supporting device for causing the counterelement to penetrate into the fiber bale underneath the tie to countersupport the tie during severing of the tie by the severing device.
摘要:
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.

A bale opener has an opening device arranged for a horizontal back-and-forth travel above a row of fiber bales. The opening device includes two parallel-arranged and horizontally oriented opening rollers provided with teeth. The opening rollers are spaced from one another in a direction parallel to the direction of back-and-forth travel and each opening roller has an axis of rotation oriented perpendicularly to the direction of the back-and-forth travel. The opening device further has a bale hold-down device through which the teeth of the opening rollers project for penetrating into upper faces of the bales and a suction device for removing fiber tufts detached by the opening rollers. The opening rollers are codirectionally rotated during the back-and-forth travel of the bale opener.

A bale opener includes a carriage arranged for a back-and-forth travel in a path along a fiber bale series; a tower supported on the carriage and a cantilever mounted on the tower and arranged for vertical displacements with respect to the tower, an opening device supported in the cantilever and arranged for removing fiber from the bale tops during travel of the carriage; a sensor assembly arranged for travel along the fiber bale series for emitting first signals characterizing bale heights; and a control device operatively connected to the sensor assembly for receiving the first signals. The sensor assembly comprises two sensors mounted on the tower or the cantilever and spaced vertically from one another. There is further provided a length position determining device for generating second signals representing longitudinal positions of the cantilever along the travel of the carriage. The length position determining device is connected to the control device for receiving the second signals.

A bale opener assembly includes a travelling apparatus detaching fiber tufts from surfaces of fiber bales supported along the travel path; and a fiber tuft removing apparatus for removing the fiber tufts from the travelling apparatus by suction. The fiber tuft removing apparatus has a stationary suction channel extending along the travel path and having a longitudinal aperture oriented generally parallel to the travel path; a flexible cover belt stationarily covering major length portions of the longitudinal aperture; a guide mechanism mounted on the travelling apparatus for deflecting the cover belt away from and then back onto the longitudinal aperture, whereby in the suction channel a fiber tuft intake opening is provided which co-travels with the travelling apparatus and through which fiber tufts are introduced into the suction channel from the travelling apparatus during operation. The longitudinal aperture is provided laterally along the suction channel and the cover belt is, along the longitudinal aperture, oriented at an angle to the horizontal other than zero.

In a coiler plate for sliver-coiling devices, especially of draw frames and carding machines, having a sliver channel with an inlet and an outlet for sliver and having a rotary plate, there is present on the underside of the rotary plate a cover which has a through opening. In order to create a coiler plate in a simple manner, a connection piece having a through opening is formed integrally with the cover by deformation.

摘要:
An apparatus for securing danger zones in a bale opening system. The apparatus includes a first beam transmitting/receiving device and a beam guide for guiding the first beam in a generally U-shaped course. A space between the legs of the U-shaped course accommodates conveyor belts on which bales are supported, the bale opener in any position along a path of travel thereof, a shuttle carriage in any position along a path of travel thereof and at least one part of a loading station. The shuttle carriage travels between a loading station where a bale is loaded on the carriage and a location on a conveyor belt where the carriage deposits the bale. The apparatus further has second and third beam transmitting/receiving devices for generating and detecting second and third beams each having a course connecting legs of the U-shaped course in a zone of the loading station. The second beam is more remote from the base of the U-shaped course of the first beam than the third beam. A switching arrangement selectively activates and deactivates the second and third beam transmitting/receiving devices.

A bale opener includes an opening roller arranged for travel over fiber bales, opening elements on the opening roller arranged to engage top faces of the fiber bales, a grate travelling with the opening roller and formed of a plurality of parallel spaced grate bars each having opposite first and second ends and an arm rigidly connecting the first ends of the bars. The arm is supported for pivotal motion about a generally horizontal axis. The grate is open at the second ends of the grate bars, and the opening elements project between the grate bars towards the bale top. An abutment is supported in a swinging path of the second ends for constituting a stop cooperating with the second ends for determining a limit of their swinging path.
