Cleaning of glue combs
For the production of wooden trusses which are particularly used as a static and optical element in building projects, a number of wooden boards are provided with a profile at the upper side and lower surface and then glued together. For this wood glue is applied on the profile by means of the glue combs (see above) and then with a „hardener comb“ (comparable geometry) a hardening agent is applied. The „tines“ of the glue combs apply the glue very exactly. Then the individual boards are stacked and injected mechanically. During production the glue and hardener combs have to be cleaned again and again since they are clogged with drying residues (see left area of the picture above) and so they cannot apply exactly and evenly.
So far these combs are cleaned in the absence of alternatives either mechanically or with a high pressure cleaner. Both cleaning methods cause a deformation of the tines. The effort for lining up resulting from it leads to additional time delays.
By the low pressure and the high temperatures we have been able to achieve really good and fast cleaning results with a 1000 SR and the cleaning agent 1000 HDF without damaging the tines. These tools were produced of V4A material.
