摘要:
The present invention discloses a method for producing a portable data carrier using a continuous production method, in particular a roll-to-roll process. At least one foil to be processed is provided as rolled material. The unwound foil is at least partially coated with an adhesive on at least one side. The foil is subsequently scored along at least one folding edge on at least one side of the foil. The foil is then folded and agglutinated along the scored folding edge in a custom-fit manner. The foil is folded towards the side, which is coated with adhesive, wherein the side coated with adhesive is arranged on the opposite-lying side of the foil, which has at least one scored folding edge along which folding occurs. Finally, data carriers are punched out in a custom-fit matter from the at least one folded and agglutinated foil.

The invention relates to a self-adhesive RFID-label provided with a printable strip-shaped or sheet-shaped cover material (1), the rear side of which is provided with an adhesive layer (2), and a backing material (3) which covers the adhesive layer (2) of the cover material (1) and can be removed, as well as an RFID inlay (4) that is made of a sheet-shaped or strip-shaped inlay material (5), the rear side of which is provided with an adhesive layer (6), an RFID chip (8) and an RFID antenna (7) being arranged on the rear side of said RFID inlay. Said RFID inlay (4) is arranged between the cover material (1) and the backing material (3), and the upper side of the RFID inlay is firmly glued to the adhesive layer (2) of the cover material (1). According to the invention, the same material is used for the inlay-material (5) of the RFID-inlay (4), including the adhesive layer, and for the cover material (1) of the label, including the adhesive layer (2).
摘要:
A tool holder having the following characteristics: - in the chuck (7) a central transfer pipe (8) is disposed, the outlet end of which dispenses the medium to the tool (2) - on the inlet side a pipe nozzle (10) adjoins the transfer pipe (8) and forms a chamber into which on the inlet side a coupling sleeve (11) leads, which can be connected coaxially to a hollow-cylindrical passage (5) in the working spindle (4), – on the inlet side, the pipe nozzle (10) is surrounded at least over a part of the axial length thereof by a takeover pipe (12) – on the inlet side, the pipe nozzle (10) has a smaller outside diameter than the inside diameter of the takeover pipe (12), and – the inside diameter and the outside diameter of the coupling sleeve (11) at the outlet ends thereof are configured such that the end of the coupling sleeve (11) can be moved in an axial direction in the annular gap-shaped intermediate space (14) between the takeover pipe (12) and the pipe nozzle (10).
