摘要:
The present invention relates to an apparatus for producing a fiber web comprising a feeder 1 for supplying a fiber material, a plurality of fiber opening cylinders 2.sub.1, 2.sub.2, 2.sub.3, . . . 2n (n is a natural number) mounted adjacent to one another for transferring and opening the fiber material fed from the feeder 1 and having metallic wires 2a mounted to the surface thereof, a conveyor 7 arranged for receiving the opened fiber unloaded from the fiber opening cylinder 2n mounted at the outlet end, and a suction box 8 arranged beneath the conveyor 7 for drawing the opened fiber towards the conveyor 7 by a sucking action, said fiber opening cylinders 2.sub.1, 2.sub.2, 2.sub.3, . . . 2n being enclosed in a housing 3 which has fiber transfer openings 4 between any two adjacent fiber opening cylinders and a fiber releasing opening 5 for unloading the opened fiber from the last fiber opening cylinder 2n, and also arranged so that any two adjacent cylinders can rotate in opposite directions. The present invention also provides a method of producing a fiber web using the above apparatus, in which at least one of the fiber opening cylinders 2.sub.1, 2.sub.2, 2.sub.3, . . . 2n is driven to produce a centrifugal acceleration of more than 3.4.times.10.sup.5 cm/sec.sup.2 for acting on the fiber material.As a result, a fiber web which is non directional and uniform is produced. Also, a fiber web in which the containing ratio of each fiber material gradually increases or decreases to the direction of the thickness of the fiber web, will be produced from two or more different fiber materials which are different in the resistance to peeling on the last fiber opening cylinder 2n. With the use of the apparatus or method of the present invention, a fiber web can be produced which is applicable to unwoven fabrics, filters, battery separators, FRP substrates, adhesive tapes, etc.

An apparatus for attaching a tire component member to a rotating toroidal green case includes support shafts whose axes are located substantially in a plane including a rotational axis of the green case. Stitching rollers are supported by the support shafts and rotatable about the axes of the support shafts, respectively. An urging device moves the stitching rollers toward the green case to urge outer circumferences of the stitching rollers against the tire component member. A swing device serves to swing the stitching rollers to continuously move contact points of the stitching rollers with the tire component member from an axially inside to an axially outside, to attach the tire component member to the outer surface of the green case.

Provided herein are various suspension devices and associated methods and apparatus to open loops (or form opened loops) in a chain of linked products suspended from one or more suspension devices in a conveyor system. In one implementation, a suspension device for a chain of linked products includes a link support portion pivotally coupled to a conveyor, the link support portion configured to suspend a portion of the chain of linked products therefrom and comprising a lower portion downwardly extending from the link support portion. The lower portion is configured to engage a portion of a respective link of the chain upon a pivoting motion of the link support portion about a pivot axis in order to open a respective loop suspended from the link support portion to an unloading orientation for unloading.

摘要:
In an operation apparatus for a vehicle transmission in which a shift lever and a control shaft of the transmission are operably connected by a shift cable and a select cable, a shift finger is mounted on the control shaft, and shift rags engaging with the shift finger are mounted on the forward and reverse shift rails, a block plate is mounted to the control shaft. A detent pin, which is pressed and moved by the block plate when moving the control shaft for selecting the reverse shift rail, is provided. Further, the detent pin is provided with a shock absorber so that the resistance is increased at rapid operation of the block plate and decreased at slow operation of the block plate.
