Abstract

A suspension device of this invention is used to carry a linear material over a cradle receiver and release the linear material onto the receiver, comprising a suspension means, a release means and an activation means. The suspension means suspends a linear material, the release means releases the linear material and the activation means activates the release means so that the suspended linear material can be released onto the cradle receiver. The device is particularly useful when the receiver is long and/or windingly. A laying apparatus of the invention chiefly comprises such suspension devices and a rail means prepared above a cradle receiver on which the suspension devices are to be movably held.

Claims

1. A suspension device movably mounted on rail means provided above and along a laying route for laying a linear material along said laying route, comprising:

suspension means for suspending said linear material;

release means including a face edge for releasing said linear material from said suspension means; and

activation means for activating said release means by a collision of said face edge with another suspension device.

2. A suspension device of claim 1, wherein said suspension means is provided with movable hanging means for hanging said linear material and releasing same when activated by said activation means.

3. A suspension device of claim 1, wherein said suspension means is provided with hanging means for hanging said linear material with a string or the like and said release means is provided with cutting means for cutting said string and releasing said linear material when activated by said activation means.
