Mould sanders sand parts which have come out of a moulder and need to be finished and smoothed. These machines might go in line with the moulder. It might have a number of heads, three to six being the most common, and each sanding head or block could be set at different angles, sanding different parts of the moulding as it passes through; for example, picture frames, floor board mouldings, door frame mouldings, window parts, etc. Some of these machines will use the Vonnegut head (discussed under Profile Edge Sanders, above), or use Fladder wheels which have little fingers of sand paper flapping around that rotate; these Fladder wheels can get into little nooks and crannies. They can also use Scotchbrite Buffing Wheels.
Profile edge sanders can be very expensive machines. These machines will sand edge work, which can be very complicated, depending on the profile. These machines almost look like an edgebander, where a continuous belt feeds the part past the numerous sanding stations. Different applications can be done to the edge at the same time as the part passes through the machine. The various stations can be comprised of either buffing wheels and/or miniature (what we consider) wide belt sanders that can be placed at different angles to the edge for different angled work where very detailed or complicated parts require sanding. Profile sanders can also be single head machines that are completely manual. These machines look like a shaper but have a round sanding head pre-manufactured to the same profile or shape as the part that is going to be sanded. The sand paper is actually glued to this pre-manufactured head, called Vonnegut heads. The Vonnegut heads can also be used on the larger through feed profile sanders, or as well, on Mould Sanders. Profile sanders can be very long machines depending on the application and are normally very difficult to set up. Some of these can be double sided machines, capable of working on two edges at the same time, similar to the double sided edgebanders.
