Abstract

1356775 Ejecting blanks from sheet-material WUPA-MASCHINENFABKIK GmbH & CO KG 27 Nov 1972 [27 Nov 1971] 54625/72 Heading B4B A method of breaking away blanks 54 from a moving web of material comprises progressively bringing a break-away matrix 28 up to the speed of the web to make contact with one side thereof on attaining synchronous speed therewith, also bringing up to the speed of the web pairs of members 14, 20 so as to grip the associated blank and breaking away the gripped blank from the material supported on the matrix. The members 14, 20 are in the form of pins adjustably mounted on rails 10, 16 respectively, the pin 20 being axially movable against the action of a spring (22), Fig. 1 (not shown). The rails 10, 16 are mounted in carriages 36, 36<SP>1</SP> respectively which are given a circular motion by means of cranks 38, 40 and 38<SP>1</SP>, 40<SP>1</SP>. The matrix comprises a plate provided with holes corresponding to the position of the blanks and is moved by suitable mechanism such that it rises into contact with the web, travels at the same speed during the ejecting operation and then returned and lowered ready for the next cycle. The operation of the device is clearly shown in Fig. 3.
