Abstract
An apparatus for slitting elongated flexible tape longitudinally into a plurality of strips of preselected width, the apparatus including a base forming a generally horizontal tape support surface and a pair of upstanding side supports, one of which functions as a side edge guide for one side edge of the tape. A shaft is mounted transversely between the side supports, and functions to support an adjustable side edge guide for abutting and guiding the other side edge of the tape, and a cutter adjustably located to slit the tape to the preselected width and having a cutting blade and a hold-down surface adjacent the blade for slidably clamping the tape during slitting to prevent lateral tape movement.
Claims20
A portable apparatus capable of being held by hand during use for slitting an elongated strip of flexible material of predtermined width longitudinally into a plurality of strips of preselected width, said apparatus comprising:
- a base having a generally rectangular shape with longitudinally spaced front and rear ends and laterally spaced sides, said base forming a generally horizontal support surface for the strip of flexible material and including an upwardly open and laterally extending channel formed therein, said channel having a sloping wall extending from said support surface to the base of said channel and defining therebetween an edge;
- a first side edge guide fixed to said base and having a first guide surface disposed to be engaged by and extend parallel to one side edge of said strip of flexible material;
- a second side edge guide adjustably mounted to said base and having a second guide surface disposed parallel with said first guide surface, said second side edge guide being adjustable relative to said base to a position laterally spaced from said first side guide by an amount substantially equal to the predetermined width of said strip of flexible material whereby said second guide surface is engaged by the opposite side edge of said strip of flexible material;
- and
- a cutter adjustably mounted to said base and disposed laterally between said first and said second side edge guides, said cutter including a mounting block and a cutter blade removably secured thereto, a portion of said blade projecting downwardly from said block into said channel substantially parallel to said sloping wall to slit said strip of flexible material into the plurality of strips of preselected width, said block including a hold down surface disposed substantially parallel with said support surface forwardly of said channel to slidably clamp the strip of flexible material against said support surface adjacent said blade to prevent distortion of said strip of flexible material during said slitting by said blade.
An apparatus for slitting an elongated flexible tape of predetermined width into a plurality of individual strips of preselected width, said apparatus comprising:
- a generally rectangular-shaped base having front and rear ends and a passageway formed therethrough, said passageway being generally rectangular in cross-section and having an entrance end and an exit end and defining a generally flat support surface therebetween;
- first and second side supports secured to and upstanding from said base intermediate said front and rear ends, said side supports being laterally spaced apart a distance at least equal to said predeterminedl width of said tape;
- an opening formed in said base between said first and second side supports and exposing said support surface from above;
- a support shaft extending horizontally between said first and second side supports above said exposed support surface;
- an adjustable side edge guide supported by said shaft between said first and second side supports, said adjustable side edge guide being laterally movable along said shaft;
- means for securing said adjustable side edge guide in a selected position along said shaft;
- a cutter supported by said shaft between said adjustable side edge guide and said first side support, said cutter being laterally movable along said shaft;
- means for securing said cutter in a selected position along said shaft;
- an upwardly open channel formed in said support surface and extending laterally across said base below said opening and forwardly of said shaft, said channel having a chamfered edge extending downwardly and forwardly from said support surface to the bottom of said channel;
- and
- a cutting blade secured to said cutter and projecting downwardly and forwardly along said chamfered edge into said channel.
