From stitching to sealing
The company, which is based in the Lyon region, has a long and proud history.The story of the company began when Barthélemy Thimonnier became the world's first sewing machine manufacturer. In 1830, he developed his patented basic sewing machine model, the Couseuse. In the 1950s, the company was asked by a fashion designer to produce a waterproof raincoat made from PVC.
“My grandfather, Louis Doyen, who was the company's Managing Director at the time, quickly realized that this could not be done using conventional sewing machines. He added a high-frequency generator to the sewing machines and sealed the PVC film,” explained Sylvie Guinard, the current CEO. Around 10 years later, the sealing of these flexible materials laid the foundation for the Doypack®.
Doyen patented the stand-up pouch in 1963 and the company went on to become a specialist in filling and packaging technology for flexible materials. “Doypack® pouches are the future of packaging. The many benefits of these high-quality stand-up pouches make them extremely popular with manufacturers and consumers,” said Guinard.“The stand-up pouch is an effective marketing tool for brand advertising. It is lightweight and has many great features. For example, it can be resealed, is efficient in terms of logistics, is easy to handle and visually appealing.”
Filling and closing
One of the machines from Thimonnier that has been eagerly awaited by the market is the SF102. This filling and sealing machine for Doypack® pouches with screw cap is easy and flexible to operate, easy to clean and access, and has a small footprint. It is popular with manufacturers of compotes, baby food, dairy products, fruit juices, soups and sauces, as well as liquid detergents and cleaning products, liquid soaps, creams and shampoos, and even engine oil.
After the stand-up pouch has been fed in, a compact cylinder ADNGF from Festo forwards it to the filling station. The correct filling quantity is determined using electromagnetic or mass flow measurement, or a dosing pump depending on the customer's requirements. At the next station, the screw caps are screwed onto the stand-up pouches. The Festo swivel module DSM-B transports the filled and sealed pouches to a conveyor.
