Abstract (en)
[origin: EP0180937A2] A long mould of U-shaped cross-section is divided into compartments by transverse partition (8) to suit the required length of the cart sleepers. The partitions are secured by bolts (9) which engage a T-shaped nut in a correspondingly shaped groove (7) on the underside of the mould. The head of the bolt fits in a recess in the top edge of the partition so that there is no projection above the partition top surface. Each bolt is screwed into a threaded sleeve (11) under the bottom plate (5).
