DEVICE FOR WINDING EDGE TRIM

Claims

1. A device for winding edge trim, comprising a frame and a drum, wherein said drum is equipped with a rotation drive for its rotation around its own axis and a translational drive for its movement in the axial direction, characterized in that a sealing mechanism is installed at the point where said drum passes through the frame.

2. A device for winding edge trim according to claim 1, characterized in that said drum includes a conical winding section, the cross-section of which gradually increases in the direction of the drum's withdrawal from the working line; said sealing mechanism is an expanding and contracting sealing mechanism capable of self-adapting to a change in the cross-section of the drum.

3. A device for winding edge trim according to paragraph 2, characterized in that said sealing mechanism includes a plurality of sector sealing plates, which when assembled form a sealing ring, and an expansion-compression mechanism for self-adaptive expansion and compression of said sealing ring, wherein movable sealing joints are provided at the junctions of each of the plates.

4. A device for winding edge trim according to paragraph 3, characterized in that both ends of said sector sealing plate are provided with tongue and groove parts, wherein every two adjacent sector sealing plates are connected into a tongue and groove, forming a corresponding movable sealing joint.

5. A device for winding edge trim according to paragraph 3, characterized in that said expansion-compression mechanism includes several damping units, the number of which coincides with the number of sector sealing plates and which are located in a one-to-one correspondence, and said damping units are installed on said frame, and the sector sealing plates are connected to the corresponding damping units.

6. A device for winding edge trim according to paragraph 5, characterized in that said damping unit includes a compression spring, a guide rod is connected to the sector sealing plate, which is movably mounted on said frame, and the compression spring is mounted on said guide rod, and with one end rests against a support surface for the spring on said sector sealing plate / guide rod, and with the other end rests against a support surface for the spring on said frame.

7. A device for winding edge trim according to paragraph 6, characterized in that a first limiting element is provided at the end of the guide rod, remote from the sector sealing plate, and a second limiting element is provided on said frame, designed to interact with said first limiting element.

8. A device for winding edge trim according to claim 7, characterized in that the position of said first limiting element on said guide rod is adjustable, and the direction of position adjustment is parallel to the axis of the guide rod, and / or the position of said second limiting element on said frame is adjustable, and the direction of position adjustment is parallel to the axis of the guide rod.

9. A device for winding edge trim according to paragraph 6, characterized in that the initial compression of said compression spring is adjustable.

10. A device for winding edge trim according to paragraph 6, characterized in that said guide rod is a hollow shaft and is connected to an air supply device for forcing air into its cavity.
