Class 100(1) In the cutting of a web of material into lengths of predetermined size defective sections are first marked on the web during its processing stage, the marks being used subsequently during the cutting operation to indicate where further markings may be applied so that in the final stock defective sheets may be readily removed. Preliminary marking may be effected  either by the insertion of tabs into the web reel or by a unit comprising two side frames 11 (Fig. 1) between which is mounted a small printing unit including a printing disc 15. The unit is arranged to be mounted across the width of a coating machine on rods 16, 17. The device is driven by suitable gearing attached to a rotating shaft 18 driven so that the peripheral speed of the disc 15 is equal to the speed of travel of the web. The disc 15 is moved into operative position by an electro-magnet 24 operated by an operator when a defective section of the web passes. After coating, a reel 46 is mounted on a stand 48 (Fig. 7) and the web is passed through a monitoring unit 45 either along the path 49 or along the path 51. The unit 45 comprises a printing unit including printing discs 31 for applying a second mark to the edge of defective portions of the web, the discs 31 being moved into operative position by energization of a solenoid 38. If the web travels along the path 49 a photo-electric cell 40 actuates the solenoid 38 in response to the markings made on the web by the first marking operation. The path 51 is used when the preliminary markings are in the form of tabs inserted by the operator into the reel and the unit 45 is then manually actuated. After passing through the unit 45 the web is cut in lengths, by a cutter 56. A unit 55 is arranged to actuate counters 53 and 54 which count non-defective sheets and defective sheets respectively, the arrangement being such that a stack of predetermined number of non-defective sheets is formed irrespective of the number of defective sheets.

Title: Log gripping device
IPC: B27B29/08
Filed: 1953-10-22
Abstract: 726,412. Sawing. VALENTIN, B. Oct. 22, 1953 [Oct. 24, 1952; May 9, 1953; May 9, 1953], No. 29242/53. Class 145. A log-gripping device for a saw comprises a slideway 10 adjustable vertically and transversely on a carriage 1 rolling on rails 4, a pair of jaw or spike holders 13a, 14a guided in and prevented from turning by the slideway 10 and a rotary control screw 16 which is free to move axially with respect to the slideway during the gripping operation, the screw being in threaded engagement with one spike holder and freely rotatable within the other holder so as to draw the latter with it during its axial movement. As shown in Fig. 3, the upper holder 13a is in threaded engagement with the screw, the lower holder 14a is secured between a shoulder 16b and a pinned ring 17 and the screw, which is rotated by a handle 18, passes freely through a hole in the upper part 10a of the slideway. When the screw is rotated, the upper holder, being lighter than the screw and the lower holder, descends until the spike 113 entering the log G causes the resistance to downward movement to overcome the weight of the screw and lower holder and the screw then rises through the stationary nut formed by the upper holder until the lower spike enters and tends to lift the log, at which point the upper holder again moves down to sink its spike more deeply into the log. Play is allowed between the holders and the slideway so that the holders are locked by jamming diagonally across the slideway 10 and do not fall when the log is sawn beyond its middle vertical section and no longer rests on the carriage. Additional looking of the holders may be provided by a pawl 20 engaging notches 23 at the top of the screw; the pawl may be loaded by its handle 21 so that it automatically engages succeeding notches as the screw moves up. After both spikes have entered the log slightly, the upper holder may be secured to the slideway by a clamp 24 so that further rotation of the screw moves the lower holder sufficiently to raise the log from the carriage. In another embodiment, the lower holder is in threaded engagement with the screw, the upper holder is fitted between a shoulder and ring at the top of the screw and both ends of the screw pass freely through holes in the top and bottom of the slideway. In the modification shown in Fig. 4, the spike holders 111, 112 are movable in a slide 110 which, after the log is gripped by the spikes, can be raised so that the log is clear of the carriage by means of a rack and pinion 125 operated by a lever 130, the lever being held in adjusted position by a pin placed behind it in one of several holes 132 in the frame. The screw is rotated by a reversible electric motor 120 through belts 122 and pulleys 123 splined to a groove 124 in the screw.
