Method and device for attaching sealing profiles
First Claim
1. A method for attaching a sealing profile to a vehicle body part, the method comprising the following serial steps:
- pulling the sealing profile from a storage unit;
passing the sealing profile through a first buffer which compensates for differences between incoming and outgoing speeds of the sealing profile;
attaching, in an assembly unit, an adhesive strip to the sealing profile continuously after the sealing profile exits the first buffer, the adhesive strip having an adhesive layer;
passing the sealing profile with the attached adhesive strip through a second buffer which compensates for differences between incoming and outgoing speeds of the sealing profile; and
attaching, in an application unit, the sealing profile to the vehicle body part by rolling the adhesive layer onto the vehicle body part along a line provided for attaching the sealing profile,wherein the sealing profile runs from the storage unit to the application unit in one continuous run, whereby both the attaching of the adhesive strip to the sealing profile and the attaching of the sealing profile to a vehicle part occur in the one continuous run of the sealing profile.

Abstract
A method for attaching a sealing profile to a vehicle body part includes the steps of pulling the sealing profile from a storage unit; passing the sealing profile through a first buffer which compensates for differences between incoming and outgoing speeds of the sealing profile; attaching an adhesive strip to the sealing profile continuously, the adhesive strip having a first adhesive layer facing the sealing profile and a second adhesive layer facing away from the sealing profile; passing the sealing profile with the attached adhesive strip through a second buffer which compensates for differences between incoming and outgoing speeds of the sealing profile; and rolling the second adhesive layer onto the vehicle body part. The adhesive strip is attached to the sealing strip in an assembly unit which heats the first adhesive layer as it moves around a press roller.

6. An apparatus for attaching a sealing profile to a vehicle body part, the apparatus comprising:
-
a storage unit for storing the sealing profile; means for pulling the sealing profile from the storage unit in a downstream direction; a first buffer downstream of the storage unit, the first buffer compensating for differences between incoming and outgoing speeds of the sealing profile; an assembly unit for attaching an adhesive strip to the sealing profile downstream of the first buffer; a second buffer downstream of the assembly unit, the second buffer compensating for differences between incoming and outgoing speeds of the sealing profile; and an application unit for attaching the sealing profile to the vehicle body part comprising press rollers to press the sealing profile continuously along a surface of the vehicle body parts following a predefined installation line, wherein the apparatus is arranged so that the sealing profile runs from the storage unit, through the first buffer, the assembly unit, and the second buffer, to the application unit in one continuous run, whereby both the attaching of the adhesive strip to the sealing profile and the attaching of the sealing profile to a vehicle part occur in the one continuous run of the sealing profile. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16)
