Abstract: 422,330. Making match books. MASSA, O., and LOUPIAS, C. V., 760, Avenida Roque Saenz Pena, Buenos Aires. July 12, 1934, No. 20448. [Class 94 (i)] [See also Groups VII and XXXVII] A continuous strip of match stock 7, Fig. 1, with the heads of the matches already prepared is fed from a spool 5, while a wrapping strip 3 having two friction surfaces fed from a spool 2 is folded over the heads of the matches by a doubling guide 9 and the matches are sewn thereto on a platform 11. The matches are then separated, either by a longitudinal knife 40 which cuts off the base of the strip or by a transverse knife working in synchronism with the sewing machine. Suitable lengths of the resultant strip are cut off and fed to a machine, Fig. 11, where they are applied to a rotating hub 153 and rolled into the form of a spiral. The finished roll may be packed in a container, the matches being ignited as they are withdrawn. Sewing and cutting operations. The strip is carried along the platform 11 by a feeder 87, Figs. 4, 5 having two parallel arms 83, 85 provided with teeth which respectively pass between the matches and engage the wrapping strip. One stitch is made between each pair of adjacent matches, and a toothed wheel 18 geared to the shaft 13 of the sewing-machine counts the stitches and after each complete revolution actuates an electric switch by the engagement of a cam 25 with a lever 22 to bring about the operation of the guillotine 53 for severing a length of the completed strip 51. The cam 25 swings the lever 22 in a counterclockwise direction, Fig. 6, and when the engagement ceases, the lever 22 recoils due to springs 93 and strikes a second spring-controlled lever 20 which moves the metal head 99 momentarily into contact with the carbon bed 102, thus energizing an electromagnet which controls the guillotine. When a transverse knife is used to separate the matches, the knife 110, Fig. 7, is moved up and down by means of the rocking shaft 42 which controls the vertical needle shaft of the sewing-machine. Automatic stopping. The thread 179, Fig. 8, is fed through a slide 114 supported on vertical pillars 116. A knot in the thread is unable to pass through the slide and lifts it out of contact with the arm 120, thereby allowing a pendulum 119 to tilt and operate a mercury switch 117. An electromagnet 124 thereupon energizes and controls a rocking arm 128 to apply a band brake 129 to the shaft 13 of the sewing-machine. The electromagnet energizes also when the match strip fed from the spool 5 is exhausted due to the bridging of terminals 139, Fig. 10, by a contact member 141 when the end of the strip has passed beyond the blocks 138, 140 between which it is fed. Rolling operation. The hub 153, Fig. 11, on which the end of the strip to be rolled is placed by an operator is in the form of a truncated cone and is clutched by pins engaging in slots in a disc 156 to a shaft 157 which is in turn coupled to a rotating shaft 183. A curved arm 168 is pressed against the roll by a spring, and when the strip is fully wound, an arm 166 is depressed so as to decouple the shaft 157 from the driving shaft 183 and bring the hub to rest. The rolled strip is ejected by moving the hub to the right past an apertured plate 155 by means of a hand lever 172 which has a pin and slot connection with the shaft 148 of the hub.
