Automate Gasket Insertion in Windows and Doors

Article from “Profiel”

In an era where qualified personnel are increasingly difficult to find, automating work processes has become a crucial strategy for companies. One area where automation can deliver significant benefits is the insertion of gaskets in windows and doors. Gasket insertion is a highly labor-intensive and time-consuming task that can be perfectly automated with Tryma machines. Tryma has long collaborated with the German manufacturer Lemuth to provide these solutions.

Gasket Insertion in Profiles

The DAGL machine provides an automated solution for inserting both frame and glazing gaskets into profiles made of PVC, aluminum, or wood. This can be done on full-length profiles as well as pre-cut and processed profile sections.

The standard machine comes equipped with a feed roller conveyor, an insertion unit with gasket heads for each gasket type, and an automatic output storage. All profile types are pre-programmed into the machine. Operation is remarkably simple, as the machine runs automatically once the operator selects the profile type via the touchscreen. The positioning of the gasket heads is fully automatic, with no manual intervention required.

The operator places the profile on the feed roller conveyor and moves it into the machine. The machine then automatically transports the profile, inserts the gaskets, and detects the profile length so that the gaskets are cut at the end. The finished profiles are delivered onto an automatic output table. One of the main advantages is the consistent quality delivered every time. Gaskets are inserted evenly along the full length of the groove with the correct amount of material. The compression factor can be adjusted per gasket type via the control screen. Both frame and glazing gaskets in a sash profile are inserted simultaneously, providing a significant time savings.

Gasket Insertion in Assembled Elements

In addition to inserting gaskets in profiles, Lemuth also provides a solution for automatically and continuously inserting gaskets into fully assembled windows and doors. A typical setup combines a CNC-controlled 4-head corner press with a gasket insertion machine for pressed frames and sashes.

Both machines can be connected so that pressed elements are automatically transported to the gasket insertion machine. Gaskets are inserted continuously around the perimeter and processed in the corners if necessary. The cycle time for an element measuring 1,000 x 1,200 mm is approximately one minute.

The standard machine features an automatic feed table, a gasket insertion unit with up to four heads, a turning system to tilt sashes onto the other side, and an automatic output table. Each machine is customized to the customer’s requirements, including desired capacity, maximum element dimensions, and the types of profiles and gaskets to be processed. Optionally, the machine can be connected to a manual or automatic buffering and sorting station.
