Abstract

1402668 Sewing machines; work cutting DURKOPPWERKE GmbH 16 Aug 1973 [21 Aug 1972] 38657/73 Heading DIG [Also in Division B4] Cutters Z used for cutting V-shaped slits at each end of a pocket opening in a garment, each comprise two blades 27, 28 set at an angle to each other. They are raised to penetrate and cut the material from underneath, by equal amounts if both limbs of the "V" are equal, or by different amounts if they are to be unequal. In addition the support for the blades is rotated when the cuts are to be unequal. A vertical rod 21 is raised by springs 32, 32' when air is released from a cylinder 25 in which the rod 21 slides, and two further rods 22, 23 attached to the first rod by springs 34, 35 are thus also raised. The blades are mounted on these two rods. Two stop-plates 38, 39 each have a stepped profile and determine how far the blades are raised. If the V slit is to have equal length limbs stop-bars 40, 41 carried on The rods 22, 23 respectively abut the same step d, d' respectively on the stopplates. For different length slits the rods, blades etc pivot through e.g. an angle # (Fig 5) and the stop-bars 43, 41 abut different steps (e.g. a g' Fig 7) thus permitting the blades to be raised to different heights. To limit the rotation of the rods, blades, etc, bolts 51, 57, 58 are provided (Fig 5). One of these is raised into its respective bore 52, 59, 60 in a plate 20 which pivots with the rods. If none is raised a bolt 55 in its bore 56 limits the rotation of the plate. Using a piston and cylinder arrangement 54 the plate can be pivoted clockwise or anti clockwise from its centre position to allow unequal cuts to be made first in one side of a garment, then in the other,
