  • Shaft 36 has a substantially truncated-cone-shaped top shank 40 projecting upwards from frame 9 to engage a tool spindle (not shown) of a machining centre (not shown) which rotates shaft 36, and therefore shaft 35, about respective axes 10 and 31.
  • the two trimming tools 34 are associated with two known vertical tracers 41, which are each mounted on one of slides 21, 22, are aligned with each other in direction 8, are located, in use, on opposite sides of work component 2 in direction 8, and engage faces 4 of component 2.
  • the thrust exerted on tracers 41 and, hence, on slides 21, 22 by component 2 substantially equals the thrust exerted on slides 21, 22 by relative actuating devices 25, 26, so that trimming tools 34 correctly follow the contour of faces 4 of work component 2.
  • Each tracer 41 is fitted in sliding manner to relative plate 23, 24 to move linearly in direction 8 with respect to relative plate 23, 24 and under the control of an adjusting screw 42 engaging relative plate 23, 24, so as to selectively control the position of tracer 41 when setting up unit 1.
  • the two trimming tools 34 are also associated with a known front tracer 43, which extends about shaft 35, is fitted in axially fixed manner to uprights 14 in direction 8, and engages edge 5 of work component 2.
  • a known front tracer 43 which extends about shaft 35, is fitted in axially fixed manner to uprights 14 in direction 8, and engages edge 5 of work component 2.
  • Tracer 43 is fitted in sliding manner to uprights 14 to move linearly in direction 15 with respect to uprights 14, so as to selectively control the position of tracer 43 when setting up unit 1.
  • Plates 23, 24 also support respective known edging strip scraping tools 44, which are fixed to relative plates 23, 24 to scrape the longitudinal edges 7 of edging strip 6 trimmed by trimming tools 34, and are associated with a known front tracer 45, which is coplanar with tracer 43, is fitted in axially fixed manner to uprights 14 in direction 8, and engages edge 5 of work component 2.
  • a known front tracer 45 which is coplanar with tracer 43, is fitted in axially fixed manner to uprights 14 in direction 8, and engages edge 5 of work component 2.
  • Tracer 45 is fitted in sliding manner to uprights 14 to move linearly in direction 15 with respect to uprights 14, so as to selectively control the position of tracer 45 when setting up unit 1.
  • the two edging strip scraping tools 44 are associated with two known vertical tracers 46, which are each mounted on one of slides 21, 22, are aligned with each other in direction 8, are located, in use, on opposite sides of work component 2 in direction 8, and engage faces 4 of component 2.
  • the thrust exerted on tracers 46 and, hence, on slides 21, 22 by component 2 substantially equals the thrust exerted on slides 21, 22 by relative actuating devices 25, 26, so that edging strip scraping tools 44 correctly follow the contour of faces 4 of work component 2.
  • Each tracer 46 is fitted in sliding manner to relative plate 23, 24 to move linearly in direction 8 with respect to relative plate 23, 24 and under the control of an adjusting screw 47 engaging relative plate 23, 24, so as to selectively control the position of tracer 46 when setting up unit 1.
  • each tracer 46 is fitted with a rail 48 extending parallel to direction 8 and supporting a slide 49, which is fitted in sliding manner to relative tracer 46 and has a known glue scraping tool 50 for scraping off any leftover glue on component 2.
  • Slide 49 is movable in direction 8, with respect to tracer 46 and under the control of an actuating device 51, between a rest position (shown by the continuous line in Figure 2 ), in which glue scraping tool 50 is located a given distance from component 2, and a work position (shown by the dash line in Figure 2 ), in which glue scraping tool 50 engages component 2 to scrape off the glue.
  • Device 51 comprises a spring 52 interposed between tracer 46 and slide 49 to hold slide 49 normally in the rest position; and an actuating cylinder 53 fixed to slide 49 and having an output rod 54, which extends parallel to direction 8 and engages a bracket 55 projecting laterally from tracer 46 to move slide 49 into the work position in opposition to spring 52.
  • unit 1 Operation of unit 1 will now be described with reference to Figure 4 , and as of the instant in which slides 21 and 22 have been moved with respect to each other so that trimming tools 34 engage longitudinal edges 7 of edging strip 6, vertical tracers 41 engage faces 4 of component 2, and front tracer 43 engages edging strip 6 and, hence, edge 5.
  • edges 7 are trimmed ( Figures 4b and 4c ) by a machining operation.
  • trimming tools 34, vertical tracers 41, and front tracer 43 are disengaged from component 2, and unit 1 is moved so that edging strip scraping tools 44 engage edges 7, vertical tracers 46 engage faces 4 of component 2, and front tracer 45 engages edging strip 6 and, hence, edge 5.
  • Unit 1 is then moved along edging strip 6 in direction 56 to first finish edges 7 by means of edging strip scraping tools 44, and then remove any leftover glue by means of glue scraping tools 50 ( Figures 4d and 4e ), which are moved into the work positions to engage faces 4 directly and avoid jamming against edge 5.
  • Unit 1 has several advantages, mainly due to the fact that:
