As shown in fig. 2, a disposable medical three-layer mask was produced. The mask main body part (1) with folds (4) can be manufactured by clamping filter paper by two layers of non-woven fabrics; and the three layers are welded together by ultrasonic waves, and a nose bridge strip (2) is still buried at the nose bridge.

Preferably, as shown in fig. 2 and 5, the headband (6) and the direction (i.e. the trend) of the long side (10) of the mask main body part (1) are synchronously applied on the mask main body part (1) without welding the ear band (3) to the mask main body part (1); two ends of the head band (6) are welded at two ends of the mask main body part (1); aligning the tail end (9) of the head band (6) on the bonding point (5) with the wide edge (8) of the mask main body part (1); for example, the headband (6) and the mask main body part (1) are cut off together by the same knife, so that the alignment can be ensured; the boundary line (11) of the head band (6) and the bonding point (5) is far away from the wide edge (8) by 1-24 mm; for example, the adhesive joint (5) is made larger and longer, so that the boundary line (11) of the adhesive joint (5) is kept 1-24mm away from the wide side (8).

It should be noted that, in the existing flat mask shown in fig. 1, the end (9) of the headband (6) on the adhesive point (5) is 10-15mm away from the wide side (8), and the boundary line (11) between the headband (6) and the adhesive point (5) and the wide side (8) of the mask are designed to be coincident, which results in complex, inefficient and high investment in the welding process of the ear band (3) or the headband (6).

Preferably, the maximum stretch length L of the headband (6) is selected for use₂Nature of the headband (6)Length L₁The ratio L of₂/L₁Elastic band not less than 2.35. The natural length of the head band (6) is substantially equal to the long side (10) of the mask body (1). And the line-releasing speed of the head band (6) with the natural length is synchronized with the advancing speed of the mask main body part (1).

Preferably, as shown in fig. 6, the natural length of the headband (6) is made larger than 150% of the long side (10) of the mask body (1). And the line-releasing speed of the head band (6) with the natural length is higher than the advancing speed of the mask main body part (1) by 150 percent.

Preferably, the maximum extension length L of the headband (6)₂The natural length L of the headband (6)₁The ratio L of₂/L₁In the range of 2.35-7.35, so that the headband (6) can be worn on the heads of various people with moderate tightness and comfortable feeling after being stretched.

Because the design is changed, the ear belt (3) is changed into the head belt (6) and the head belt (6) is paid off synchronously with the advancing speed of the mask main body part (1), the bonding speed is greatly improved, the production efficiency is improved, and the manufacturing cost is reduced.

In order to further increase the bonding speed, it is preferable to customize an elastic band containing a low-temperature hot-melt adhesive component for use as a headband (6) for rapid welding using existing ultrasonic welding machines.

Example two.

When a consumer needs to wear the mask, the user can pull up the head band (6) and put the head band (6) of the plane mask manufactured by the previous example on the head, which can be efficiently produced, so as to fix the mask at the mouth and nose, as shown in fig. 3.

Example three.

If the consumer likes the ear belt (3) and dislikes the head belt (6), the user can cut off the head belt (6), and as shown in fig. 4, the head belt (6) is knotted by a knot (7) and is changed into the ear belt (3) for use. Preferably, the headband (6) is long, so that the length of the ear band (3) is still sufficient even if a knot (7) is tied after the cutting.
