Fitschenband , also called Fitschband , Fischband or Einemmband , is a band that was used in the craft ( carpenter ) door , window and furniture construction .

If doors and door leaves are mentioned in the following, the information also applies to door and window sashes, shutters, flaps, gates, etc.

The part of the tape that disappears into the wood is called the “lobe” or “tab”, the part that remains visible is called the “roll”. The outer end of the roll was often provided with decorative buttons, for example in the shape of an acorn .

Fitschen tapes are usually used with rebated doors, as the slots can be mortised by the rollover at a sufficient distance from the edge. In the case of flush door leaves, the slots for the hinge tabs would have to be cut at an angle in the wood, which means more effort to position the slots and align the door leaf. Flush door leaves are therefore usually provided with screw-on hinges that are screwed onto the narrow side of the door leaf and the rebate of the frame. Screw-on bands differ only slightly from the Fitschen bands . Your hinge loop is as Screw-on or Einfräslappen executed. The latter is inserted a little deeper into a flat milling contour in order to lie flush with the surface of the door rebate. These belts are also referred to collectively as roller belts , since, in particular, when the door is closed, only the cylindrical belt roller is usually visible.

Differentiation between Fitschenbänder and screw-on bands on the basis of the band flaps

  • The tabs of Fitschenbänder are often bevelled on the flat side and the narrow side to make them easier to turn.
  • The strap lugs of Fitschenbänder mostly have only two holes for driving the pins. No more are required, since the flap is already fixed relatively well by being knocked into the slot. The straps of screw-on hinges, on the other hand, usually have three, four or five bores, which are usually designed as countersunk holes so that the heads of the countersunk screws used are flush with the surface.
  • Since the straps of the screw-on hinges are visible when the door is open, they are often made with a more even and high-quality surface.
  • The straps of screw-on hinges are almost in one plane when they are aligned parallel. The distance between the outer surfaces of the tabs then corresponds to the intended air gap in the door rebate of usually 1 to 3 mm. With milling tabs, the distance between the inner surfaces of the tabs corresponds to the air gap. In contrast, the strap tabs of Fitschenbänder are usually more than one centimeter apart when they are aligned parallel.

To mortise the hinges, slots are cut into the wood of the door leaf on the one hand and the frame or frame on the other hand with a circular saw blade, milling disk or manually with a fitting iron . The tape tabs are inserted into the slots, which are then fixed in place by driving Fitschen tape pins (similar to shortened nails without head ) through wood and pre-drilled holes in the tape tab. Alternatively, screws can also be used, but their heads are less easy to conceal in the wood.

Fitschenbands were widely used until the early 1960s. They are still occasionally used in historic and listed buildings as well as in period furniture and restoration projects.

Fitsch band iron

The Fitsch band iron, or Fitschen iron for short, which is specially designed to make the slots by hand, is similar to a chisel . However, it does not have a continuous blade. Instead, the two narrow long sides each end in a point. The prongs are used to cut through the wood fibers by alternately hammering in and moving the Fitschen iron and to clear them from the resulting slot to the surface. Fitschen irons are available in several strengths that are used to match the thickness of the selected bands.

  • Fitscheneisen

  • Bottom of fitschen iron; the little hooks help to get the chips out of the slot
