The plastic tube or workpiece passes continuously over the table (1). The gap (3) aligns with the nip of the conveying roller pair it accommodates. The lower roller (4) is a counter-roller, the upper (5) is a suction cylinder (6) working with the supply roller (7) sheet feeder (8). A wide slot nozzle (30) introduces a flow of temperature-controlled hot air into the nip. The temperature immediately following adhesion, resulting in good bonding, is used as a desired value, to control the temperature of the heated air. Preferred features: The temperature at the adhered region is measured as an actual value, directly after adhesion. The air temperature is raised or lowered until its value corresponds with the desired value. The temperature of the device is measured, and the air temperature is pre-adjusted correspondingly. |
