Patent number: 9993981Abstract: There is disclosed a cutting mechanism for severing elongate fiber reinforcement material in composite material lay-up equipment, the cutting mechanism comprising a cutting element and a counteracting element which cooperate to sever fiber reinforcement material extending through the nip between them, the cutting element being mounted on an elongate arm which is pivotable about a pivot axis A spaced from the nip, to displace the cutting element relatively to the counteracting element to perform a cutting stroke, the mechanism further comprising guide means arranged to guide the fiber reinforcement material through the nip in a feed direction transverse to the pivot axis A, and an actuation device for driving the elongate arm in a cutting stroke, the actuation device acting on the elongate arm at a position away from the cutting element. There is also provided composite material lay-up equipment comprising the cutting mechanism.Type: GrantFiled: June 8, 2015Date of Patent: June 12, 2018Assignee: COMPOSITE TECHNOLOGY AND APPLICATIONS LIMITEDInventors: Anthony Dale Johnson, Ralph Douglas Cope, John Anthony Kukon, Michael James Case, James Tingle
