The present invention relates to a laying machine for laying at least one flexible casing or tube, cable or wire including: a blade arrangement for making a trench in the ground, a consolidation and laying means being arranged behind the blade arrangement, for clearing and safe-guarding the trench from collapsing while laying at least one flexible casing or tube, cable or wire into the trench. A blade assembly comprising compartments for cooling fluid and air.

Laying machine and a blade assembly

A spacer structure () for a saw disc assembly of a sawing machine (), comprises a hub device () having a central axis and being adapted to be coaxially arranged between a pair of axially peripheral saw discs. According to the invention, said hub device () is configured and adapted to detachably or non-detachably receive a proximal portion () of an elongated spacer means () in a substantially radial manner in relation to said hub device, said elongated spacer means () being adapted to be arranged between said pair of saw discs, a distal portion () of said elongated spacer means () being constituted and adapted to detachably or non-detachably connect to said pair of peripheral saw discs.

Spacer structure for a saw disc assembly and a saw disc assembly

An abrasive disc () for grinding and/or polishing hard floor surfaces of stone, concrete or similar, the abrasive disc including a plurality of fixing means () for mounting detachably mountable carrier plates (), each with abrasive elements (), to a grinding side () of the abrasive disc (), each carrier plate having a specific fixing geometry, characterized by that the fixing means are disposed at least two separate distances from the centre of the disc, first fixing means () at a first predetermined distance (r) and second fixing means () at a second predetermined distance (r), said second predetermined distance (r) being shorter than the first (r), so that the carrier plates () will be arranged in at least to rows, a first outer row and a second inner row, and each fixing mean () includes a groove () providing a female coupling adapted for corresponding male couplings of the carrier plates ().

Double row abrasive disc

The present disclosure presents a laying machine for laying at least one flexible casing or tube, cable, or wire. The laying machine includes a blade arrangement for making a trench in the ground. The laying machine can also include a consolidation and laying means being arranged behind the blade arrangement for clearing and safeguarding the trench from collapsing while laying at least one flexible casing or tube, cable or wire into the trench. Additionally, a blade assembly including compartments for cooling fluid and air is presented herein.
