  • the band-shaped material can - after the individual profiles have been arranged in particular to form a floor covering next to each other - are applied in a simple and practical manner on the end faces, similar to a known edge bath, which is applied to a furniture board.
  • the band-shaped material is used in systems with profiles which have a profile body which is designed as a solid profile or full profile body, wherein the band-shaped material is applied to the end faces of these profiles.
  • the band-shaped material is preferably at least partially made of a polymer material, which can be converted at least partially into a molten state by heating, so that the band-shaped material can be bonded to the front sides in a materially cohesive manner and by heating, to form a plurality of profile end sides together with a face cover single band and in particular to close open profile front sides moisture-tight by this band.
  • the band-shaped material can usually be tailored on site to the particular application and heated, for example, with hot air, so that a preferably complete cohesive connection or bonding of the tape or the band-shaped material with the end faces can be realized.
  • the band-shaped material can also be punched out adapted to the particular application.
  • a piece of a profile which in particular can be a piece of two pieces, which are present after cutting or severing the profile in the longitudinal direction, to be a part or a component of the system according to the invention in the form of a closure profile .
  • the cut side or longitudinal side of the closure profile may have a recess which formed a part of a hollow chamber of the profile hollow body before cutting.
  • a longitudinal side of the edge of the system according to the invention can also be launched with the band according to the invention, together with the creation of a visually appealing system edge.
  • the band or the band-shaped material also profiles with a profile hollow body can be imparted a full profile character, in particular also because an at least substantially seamless connection of the band-shaped material or the band to the profiles is possible.
  • the color and shape of the tape or the band-shaped material can be chosen arbitrarily and individually.
  • the band or the band-shaped material may be adapted to the appearance of the profiles or the profile body and / or printed in color, thereby setting accents.
  • the band-shaped material may have at least one side in the form of a visible side, which is visible after the application of the band-shaped material on the end faces, wherein the visible side can be optically adapted to the surface, in particular the outer surface of the profile body or the profiles.
  • the visible side can also be colored, e.g. printed in color, to set accents and / or visually stand out from the outer surface of the profile body or the profiles.
