Abstract
The present system for joining tape leaders is comprised of an elongated member which has a finger like protrusion and a cam protrusion both of which are disposed close to one end thereof. The elongated member has an elongated slot at one end which fits over a stud and is further rotationally coupled to a crank so that the elongated member can pivot around said stud in a number of different positions in response to the crank being moved. The crank is rotationally coupled to a cam follower and the crank is further arranged to rotate about a stud.
Claims10
A mechanism for joining a first tape leader with a second tape leader, said first tape leader having one end secured to a take up tape reel and a second end with a tab supported by a stem section that is narrower than said tab, said second tape leader having one end connected to tape on a supply tape reel rotatably positioned within a housing and a second end with a locking slot therein, wherein said locking slot comprises a first portion sized to permit said tab to pass therethrough and a second portion toward the second end of said second tape leader, said second portion sized to prevent said tab from passing therethrough, while permitting said stem section to pass therethrough, whereby, upon locking said first and second tape leaders together, tape may be transferred between said take up tape reel and said supply tape reel along a tape path, said mechanism comprising:
- means for positioning said first tape leader substanially within the tape path, and means for guiding said housing from and inactive position to an active position such that the movement of said housing to the active position causes said tab of said first tape leader to enter and extend through said first portion of said locking aperture so that rotation of the take up reel to pull said first tape leader draws said stem section into said second portion of said locking aperture to thereby lock said first and second tape leaders together.
An arrangement to automatically lock a leader of a supply tape with a leader of a take up tape comprising in combination:
- a quantity of supply tape means having a supply leader section, said supply leader section having an aperture therein;
- reel means having said supply tape means wrapped thereon;
- housing means having an upper section and a lower section and holding said reel means for rotation, said housing means formed to have a curved inner wall in said upper section whereby said supply leader section is held to be curved downward so that said aperture in said supply leader section is characterized by a substantial horizontal component;
- take up reel leader means;
- and means holding said take up reel leader means in a curved upward position to overlay said aperture in said supply leader section whereby as said take up reel leader moves downwardly it will lock into said aperture in said supply leader section.
