Appeal No. 2003-1254 Page 6 Application No. 09/284,793 retaining ruler 7 as shown in, for example, Figure 2. The wedge device K cooperates with a height-adjustment or height-setting device H, which is adapted to permit setting of the wedge device K at such a height in the slot 6 that the wedge device is capable of wedging up a knife blade 2 of a certain defined dimension. This height-adjustment device H may include one or more screws 13 which are screwed into the tightening ruler 9 and protrude downwards as legs through which the tightening ruler 9 engages the bottom 14 of the slot 6, or a protective strip 15 disposed on the bottom 14 of the slot 6 and made of a harder material than the material in the knife-retaining cylinder 3. The heads of the screws 13 are accessible from above so that the screws can be screwed down or up with a tool, whereby the tightening ruler 9 can be lowered or raised in the slot 6. In order to ensure that Strömberg's rulers 7, 9 and knife blade 2 remain in the slot 6 until they are wedged up therein resilient means 16 is provided to affect the rulers 7, 9 vertically relative to each other. These resilient means 16 (there are preferably a plurality thereof) are compressible by manually displacing the retaining ruler 7 upwards relative to the tightening ruler 9 until the total width of both rulers 7, 9 and the blade 2 is less than that of the slot 6. The rulers 7, 9 with the blade 2 are in this condition insertable into the slot 6, whereafter they are released. Thereby, the resilient means 16 will displace the retaining ruler 7 relative to the tightening ruler 9,Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
