The PTt is available in a variety of levels of automation

Since the introduction of the revolutionary PTt technology, the toothbrush industry has shown a

massive interest. Many machines were built over the recent years, and Boucherie has brought this new concept to full fruition, as well as developed a solid experience with the technology.

When brushes are made with this revolutionary technology, handles with conventional pre‐cored holes for the tufts are used. Pre‐endrounded filaments are picked and arranged in a pattern of tufts with a certain geometry and topography. The filaments of each individual tuft are fixed together by melting the ends together on one side. These masses of molten filament material are eventually fixed into the pre‐molded holes in the toothbrush head, by means of a combination of

pressure ( P), temperature ( T) during a certain time (t).

The product design advantages offered by PTt are very important :

‐ Because there are no head plates and no anchors, the PTt technology allows a very narrow space between the tufts and the edge of the head as well as reduced investments ( fewer molds) and a simpler production process.

‐ TPE ( “rubber”) cleaning elements between the tufts, on the outside or on the back of the head (tongue cleaner), are possible.

‐ The widest range of handle materials can be used, including transparent materials.

‐ Angled tufts are possible, in length‐, width or a combined direction

‐ The toothbrush head can be very thin, typically at least one millimeter thinner than a

conventional toothbrush, which makes for a very ergonomic toothbrush head.

The PTt fibrebox has an in‐line end‐rounding system, so there are no transfers of end‐rounded material

Combinations of tapered and cylindrical filament are possible in compact and elegant toothbrush head designs

‐ The tuft topography can be complex, with extreme length differences, with the same end‐rounding quality for the longer, the shorter filaments or the obliquely configured filaments. For this technology, this does not have any complexity‐ or cost implications : there are no hard

to maintain profiled trimming devices, there are no spreading systems as there are for conventional tufting technology.

Combinations of tapered and cylindrical filament are possible in compact and elegant toothbrush head designs

‐ Tapered filaments can be processed, also in combination with standard cylindrical filaments.

‐ Tufts of the most varied sizes and shapes can be combined. The PTt machine is available as a manually loaded machine, or with all the automation features that will cut down your labor cost factor:automatic handle feeders, automatic fiber loading systems, 5‐colour fibrebox, hotstamping, decal stamping, laser coding, … et cetera, all the way to integrated packaging or palletizing。
