Embodiment Construction

[0038] The figures serve to illustrate the method according to the invention for producing a tensioned sheet or similar protective cover. In this case, rectangular bed sheet parts 9 are cut out from the web material. Such a sheet may, for example, be hemmed all around. Also available as in figure 1 As explained in , the elastic band (Gummizüge) 10 is sewn together or on or into the seam allowance on the edge side.

[0039] as it is figure 2 As shown in , the method according to the invention is determined and suitable for forming a square-like cover 11 from such a bed sheet 9 . The particular value here is that the bridging height, ie the height of the part 11, can be determined in a simple manner and that the corner area runs exactly vertically, ie at figure 2 The line indicated by 12 in is directed vertically as precisely as possible.

[0040] In the design according to the present invention, the bed sheet 9 is spaced apart from the corner 1,5 in the area of ​​each co...

Abstract

The invention relates to a method for manufacturing fitted bed sheets, in which: rectangular sheet pieces (9) are cut; each corner (1,5) of the sheet pieces (9) is folded in on itself, the portions that are folded in on themselves are joined by a seam at a distance from the tip of the corner (1,5) of the sheet piece; and the tip projecting beyond the seam is cut off, forming a rectangular-shaped sheet piece (11), wherein the sheet piece (9) is held at each corner (1,5) at two holding points (2, 3; 6, 7), the first holding point (2; 6) on the first peripheral edge (13,13') is moved parallel toa plane covered by the sheet piece to the second holding point (3; 7) on the second peripheral edge (14,14'), together with the associated portion of the sheet piece (9); and the holding points (2',3;6', 7) are held one on top of the other and a sheet flap in the shape of a right-angled triangle is formed, said sheet flap being provided with the seam (18) along the second leg (17) of the trianglethen being cut off next to the seam (18) following the line of the latter.

Description

technical field [0001] The invention relates to a method for producing tensioned sheets (Spannbettüchen) or similar protective covers (Schonbezügen), in which a rectangular sheet piece (Tuchstücke) is cut from a web (Bahnware), the sheet Each corner of the sheet piece is placed on top of each other, and the tops of the corners of the sheet piece are spaced apart from each other by connecting the overlapping areas by a seam and separating the tops that protrude beyond the seam, thereby forming a similar square cover (Bezug ) or sheets. Background technique [0002] A corresponding method is known from DE 35 42 445 C1. For example, it is known from the cited publications to cut rectangular bed sheet parts from a web, wherein the bed sheet parts can each be provided with a longitudinal seam allowance and a transverse seam allowance. What is important for forming a similarly square cover or bed sheet is that, according to the prior art, the formation of the corner regions whic...
