DISTRIBUTING GLUE IN LARGE PLANTS
Glue is used in the wood-working industry mainly for making joints and veneers.
In large establishments, where many workmen are employed, a good plan for distributing the melted glue is to arrange a battery of small glue-pots, or warmers, strung along a pipe line running from the steam boiler or gas heater.
Individual pots of copper which are filled at the central source of supply fit into cast-iron jackets, kept warm by steam which comes from the pipe line. The requisite temperature is thus maintained at minimum cost.
The valves may be so arranged as to cut off any warmer not in use, avoiding waste of heat. The arrangement is very satisfactory even in comparatively small establishments, and may be adapted to any number of individual pots.
