Parry/ITW Clay Pantile production plant[edit | edit source]
Description
The Clay Pantile Production Plant is a further part of the ITW small-scale production plant and handling system for burnt clay building materials. It is a cost-effective, simple alternative to the traditional methods of clay roof-tile production. The production of clay pantiles with the Parry/ITW plant is a purely manual operation, in which only local materials are processed.
The main equipment is a preparation table, on which a roller press and tile stand are mounted, and on which the raw clay is shaped to pantiles and placed on special forms for drying. Furthermore a steel box with a cutting frame is provided together with a bow cutter to cut uniform clay bats, as well as a shaping tool into which the bats are placed. Most of the ITW equipment used for brick-making (eg clay crushers, portable clay hoppers, carrying racks 3-wheel trucks) are also designed for use in pantile production.
The approximate dimensions of the finished clay pantile are 350 x 270 x 11 mm thick. The effective coverage is approx. 270 x 230 mm (about 16 tiles per square metre of roof surface).

How a clay tile is made
- A clay bat is thrown into the cutting frame. The excess is cut off with the bow cutter and re-used.
- The outer box of the frame is removed by sliding upwards.
- The large bow cutter is used to cut the clay into bats. The frame has slots to guide the cutter.
- The clay bat and the shaping tool is dusted with sand and the bat is laid on the shaping tool. The surface is dusted with sand to prevent sticking.
- The shaping tool with the bat on it is rolled through the roller press. This forms the bat into the correct tile shape and thickness.
- Tile and shaping tool are placed on the stand and the trimmer is drawn along the edges to cut off the excess clay.
- The drying form is placed on top of the tile, and holding the two together is lifted and fumed over.
- The shaping tool is removed, leaving the tile in position on the drying form.
- Then it is transferred to the carrying rack.
- When full, the carrying rack is picked up by the 1/4 tome truck and taken to the drying racks.
- The forms are then placed on the covered drying racks where they harden for one or two days.
- Then they are taken to the drying ground where they are removed from the drying forms and stood on edge for final drying before firing.
