  • a guide rod 17 is attached to the table 11 and an alignment block 15 is connected to the guide rod 17 for slide movement on the table 11.
  • the alignment block 15 is fixed at an arbitrary position by fastening it with a screw 16.
  • the screw 16 protrudes from a hole 47 formed on a rear cover 18.
  • the numeral 19 designates an opening for receiving or ejecting the sheet material assemblage 12.
  • a front cover 20 is provided with a pin 20a at each side thereof and attached to the cover 14 for swing movement about the pins 20a.
  • Two pairs of vertical guide members 41, 42 are fixed on the table 11 and arranged with a distance therebetween.
  • the knife 13 is arranged between the vertical guide members 41 and 42 of each pair.
  • Each of the guide members 42, 42 is provided with an oblique guide groove 43.
  • the guide grooves 43, 43 extend parallel to each other.
  • the knife 13 is provided with rollers 44, 44 which are guided within the associated guide grooves 43, 43, respectively.
  • the knife 13 is pivotally connected at its corner to a link 33 through a pivot 46 and the link 33 is pivotally connected to a crank 32 through a pivot 45.
  • the crank 32 is coupled to a drive shaft of a motor 31 arranged within the table 11.
  • crank 32 is rotated by the drive of the motor 31, and the rotation of the crank 32 is transmitted to the knife 13 through the link 33, so that the knife 13 is moved upwardly and downwardly in an oblique direction in order to trim the sheet material assemblage 12 along an edge thereof.
  • An auxiliary plate 21 extends parallel to the alignment block 15 and is arranged between the alignment block 15 and the sheet material assemblage 12.
  • the sheet material assemblage 12 is abutted at the edge opposite to the edge to be trimmed against a surface of the auxiliary plate 21 so as to be positioned in a predetermined orientation relative to the knife 13.
  • Two parallel leg portions 22a, 22a of a U-shaped actuating rod 22 extend through the alignment block 15 and are arranged perpendicularly to the auxiliary plate 21 for movement along their axes, respectively.
  • the actuating rod 22 is connected at the tip of the leg portions 22a, 22a thereof to the auxiliary plate 21.
  • the curved portion 22b of the actuating rod 22 is upwardly bent at right angle with the leg portions 22a, 22a and serves as a handle.
  • a spring 23 is arranged in surrounding each of leg portions 22a, 22a of the actuating rod 22 between the curved portion 22b and the alignment block 15 in order to resiliently push the opposite surface of the auxiliary plate 21 against the alignment block 15.
  • the screw 16 is loosened and the alignment block 15 is slid on the table 11 along the guide rod 17.
  • the alignment block 15 is reached the position according to a predetermined size of the sheet material assemblage 12, the alignment block 12 is fixed at the position by fastening it with the screw 16.
  • the front cover 20 is opened and the sheet material assemblage 12 to be trimmed is inserted into the apparatus through the opening 19 of the cover 14 until the sheet material assemblage 12 abuts at the opposite edge thereof against the auxiliary plate 21.
  • the front cover 20 is closed and the motor 31 is driven, and the knife 13 is downwardly moved in an oblique direction to trim the sheet material assemblage 12 along the edge thereof. Then the knife 13 is upwardly moved in the oblique direction and trimming operation is completed.
  • This situation is illustrated in Fig. 5.
  • the auxiliary plate 21 is pushed against the alignment block 15 by the resilient force of the spring 23 during trimming so that the sheet material assemblage 12 is positioned in the predetermined orientation as it is trimmed by the knife 13.
  • the actuating rod 22 is manually pushed into the alignment block 15 against the resilient force of the spring 23 so as to push out the auxiliary plate 21 in a direction away from the alignment block 15, consequently, the sheet material assemblage 12 adjoining the auxiliary plate 21 is moved toward the opening 19 of the cover 14 until the trimmed edge of the sheet material assemblage 12 is pushed out beyond the knife 13. Then front cover 20 is opened, and the margin cut from the sheet material assemblage 12 is taken out. At this time, the trimmed edge of the sheet material assemblage 12 is pushed out beyond the knife 13. This situation is illustrated in Fig. 6. Thereafter, the auxiliary plate 21 is moved by the resilient force of the spring 23 to the position in which it adjoins the alignment block 15.
  • the sheet material assemblage 12 can be easily and safely taken out from the table 11 of the trimmer by means of a very simple mechanism composed of the auxiliary plate 21, the actuating rod 22 and the spring 23.
  • the position of the alignment block need not be adjusted after trimming operation.
