摘要:
The bearing unit comprises a plurality of bearing elements rotatable relative to each other. A shell encircles the plurality of bearing elements. A body of resiliently compressible material is located between the shell and the plurality of bearing elements and possesses a predetermined compressibility. This body of resiliently compressible material retains the plurality of bearing elements relative to the shell and permits free adjustment of the plurality of bearing elements relative to the shell within limits determined by the predetermined compressibility of the resiliently compressible material.

A tube-supporting cradle mechanism for a filament, especially a yarn or thread take-up system is provided with a resiliently deformable body enabling relative adjustment of relatively rigid parts which adjoin the resiliently deformable body in order to permit line contact between a bobbin tube or its package wound thereupon, which is supported by the cradle, and a friction drive roll.
摘要:
Individual fiber components are blended in accordance with the properties of a required intermediate product such as a card sliver or an end product such as a yarn. The fiber bales are combined into component groups and the fiber components in the groups are accurately supplied by metering devices to a blender in which the components are uniformly mixed. The product from the blender may be cleaned and thereafter carded into a sliver. The characteristics of the sliver, such as the color, fiber, fineness and quantity, are tested and adjustments made in the blending in dependence upon any deviation from preset values for the characteristics.

The method provides for the replenishment of fiber bales to at least one row of fiber bales disposed on a spinning floor in operative positions extending along a path of a reciprocally mounted fiber bale opening machine. The bales are assembled in groups and delivered to a standby position on the spinning floor. When required, each fiber group is moved from the standby position into an operative position.
摘要:
A bale opening machine is provided with a safety apparatus, by means of which there are produced safety barriers or fences parallel to lengthwise sides of a row of bales to be opened and/or substantially perpendicular to the direction of movement of the bale opening machine. The safety apparatus moves in conjunction with the bale opening machine. The safety apparatus can comprise mechanical and/or sensory protective structure. The sensory protective structure comprises one or more electro-acoustical transducers arranged in a sonic chute together with one or more reference reflectors such that transmitted acoustical signals are split into a measuring signal and a reference signal. The reference signal is reflected at one of the reference reflectors, whereas the measuring signal is reflected at a deflection reflector into the monitored area and back again by an object located in the monitored area.

A package former support device or package tube support device for a double-armed cradle comprises a package tube support member which is provided with a detent or latching element which operatively engages or latches in an opening or notch in the package tube to prevent relative rotation between the package tube and the package tube support member.
摘要:
A bale removal machine having sensory control protective apparatus and a process for the sensory control of the protective apparatus. During at least an initial pass of the bale removal machine along a row of bales, at least one control sensor scans and monitors an area located in the feed direction of the removal member of the machine. If the evaluating unit connected to the control sensors detects a bale, the protective curtains are deactivated immediately before a bale is detected by same. In subsequent removal passes, the protective curtains are activated and deactivated as a function of the known bale profile and/or the control sensor or sensors. If presence of a foreign object, particularly a person, is detected, protective measures are initiated by the protective curtains.
摘要:
The flock delivery system employs a microcomputer with a storage cell for each marker and a storage cell for each stretch of path (containing one or more bale groups) between the markers. The control system is conditional selectively to "permit" or "inhibit" extraction of flocks from bales in each block individually. Various flock blending combinations can be obtained from time-to-time by programming of the control system.
摘要:
A fiber bale opening device (1.1) with a bale opening organ (30) moves in the direction of the arrow A over a row of bales (4) to open fiber flocks from the surface of the bales by means of the opening rollers 6a and 6b. The opening rollers are inclined in such a way that the bales are opened with an angle .gamma. to the horizontal. The opening rollers (6a and 6b) are moreover adjustable to incline in such a way that the depth of penetration (T.1) of the leading opening roller correspond substantially to half the penetration depth (T.2) of the trailing opening roller. These penetration depths can, on the one hand, be effected by the setting of the opening rollers. Movement of the opening organ (30) in direction (D) sets of the opening rollers in order to retain the opening depth (T.1).
摘要:
The fiber flock removal apparatus has a pair of removal rolls which may be adjusted in height relative to each other to obtain different depths of penetration into the fiber bales. The removal rolls may rotate codirectionally with the direction of travel or may operate in contra-direction with respect to the direction of travel. The rolls may be mounted individually for vertical movement relative to each other or may be mounted in a common removal means which is pivotal about a horizontal axis to achieve adjustability in the relative heights of the removal rolls. In one embodiment, the rolls are maintained in a common horizontal plane while grid bars are angularly adjusted to obtain different depths of penetration of the removal rolls into the fiber bales.
