Description

Method for wrapping and applying self-adhesive tape.

The invention relates to the winding pattern of a roll of self-adhesive tape.

The invention also relates to a device and method for applying self-adhesive tape to a substrate, for example being a window frame or glass lath, wherein a freely wound roll of tape wound on the body is applied to the substrate by hand using a conductor.

10

The presently used method for applying self-adhesive tape is that the tape is attached to the substrate by hand, whereby the precision of the position relative to the substrate of the taped tape is not firmly defined. A consequence of this is that the size of the sealant to be applied later is also undefined and can be too thin or too thick. Another consequence of manual fixing is that the tire may be stretched too much, with the result that there is a greater chance of the substrate being released prematurely. Another consequence of manual fixing is that the tape is not always properly pressed along the entire length. A consequence of this is a reduced adhesion to the substrate, with the result that there is a greater risk of premature release of the substrate.

The invention will be explained in more detail below with reference to an exemplary embodiment shown in the figures.

Figure 1 shows schematically the used winding pattern for the self-adhesive tape.

Fig. 2 shows the roll holder to be carried on the body.

FIG. 3 shows the conductor.

The winding pattern seen in Fig. 1 of the roll with tape is such that there is a substantially closed side. This is achieved by winding the tape on a core 1 without axial displacement and shortly before a full revolution 2 by moving the tape bandwidth 3 axially 1037466 2, after which an almost complete revolution is made again. After the desired winding width 4 has been obtained, this pattern is continued in the opposite direction until the starting position is reached again. This cycle is repeated until the desired roll diameter is achieved.

The stability of the roll is obtained because there is a connection every 5 degrees to the adjacent winding.

The wound roll is mounted on a free-running holder, Fig. 2, which is carried on the body. The core of the roll is slid onto the free-rotating mandrel 1. The mandrel is mounted on a flexible strip 2. There are slotted holes in this strip which enable attachment to a belt.

FIG. 3 shows the guide with which the strap 1 is attached to the substrate 15. The tape 1 is glued by hand with the starting point 2.

The guide is placed over the tape and is moved over the tape with a movement from the starting point.

When used for an inner corner, the guide block finds guidance with plane number 6 against the surface 7 that is approximately perpendicular to the substrate.

When used for an outer corner, an additional supporting surface 8 is added to the block and the guide block is guided with plane number 9 against the plane 10 which is approximately perpendicular to the substrate.

The tape first passes through the 1st zone 3 that straightens the tape, the second zone 4 compresses the tape lightly and sticks it to the substrate, the third zone 5 presses the tape with a higher surface pressure so that a good adhesion is obtained.

The possible elongation of the belt in the 3rd zone 5 which is caused by the force in the longitudinal direction of the belt, generated by the normal force of the pressure zone with the friction between the block and the belt, is largely prevented by the fact that in zone 2 a bond between the tire and the substrate has been established.

With the guide a constant and high precision of the positioning is obtained and the elongation in the belt is minimal.

The method of applying self-adhesive tape consists of using the roll tape fig. 1 to be carried on the body together on the free-rolling container fig. 2 combined with the guide block. Figure 3 for inner corners or, with the addition of an additional support surface on the guide block. , for outside corners.

Claims (5)

1. A winding pattern of the roll with tape that is at least 2x tape width wide, such that a substantially closed side 5 is formed. This is achieved by winding the tape without axial displacement and shortly before a full revolution the tape width is moved axially, after which an almost complete revolution is made again. After the desired winding width has been obtained, this pattern is continued in the opposite direction until the starting position is reached again. This cycle is repeated until the desired diameter is reached. The stability of the roll is obtained because there is a connection every 360 degrees to the adjacent winding. 2. A guide block with which, relative to an inner corner, parallel and precise positioning of the tape is obtained, which is pressed over the entire length. The extension of the strap is also minimal. 3. Device as claimed in claim 2, characterized in that an additional guide strip makes the guide block applicable for outside corners. 4. A free-rolling holder for the tire roll portable on the body. 5. A method of applying self-adhesive tape by using together the roll tape fig. 1 to be carried on the body on the free-rolling holder fig. 2 combined with the guide block fig. 3 for inner corners or combined with the guide block fig. 4 for outer corners. 1037466
