An apparatus is provided for retaining lamellar material in stacked form. The device includes a sectional rail with a J-shaped cross section, which rail forms the main body of the device. The retaining action of the device is provided by a clamping rail with an L-shaped cross section. In the vicinity of its apex, the L-shaped clamping rail is pivotally mounted at the end of the shorter leg of the J-shaped sectional rail so that the longer legs of the two rails are in opposed, spaced relationship with the shorter leg of the L-shaped rail extending therebetween. An actuating member is coupled to the shorter leg of the L-shaped clamping rail and includes a threaded shaft which extends through a hole in the arcuate or web portion of the J-shaped sectional rail. The threaded shaft is capped with a wing nut which permits adjustment of the device. In operation, the stack of lamellar material is inserted between the longer legs of the two rails and the wing nut is screwed down onto the threaded shaft. This causes the shorter leg of the L-shaped clamping rail to be drawn towards the web of the sectional rail, whereby the clamping member is pivoted so that the two longer legs of the rails clamp the lamellar material between them. |
