Abstract
Abstract An apparatus for filling a cassette with a length of magnetic tape, comprising a cassette holder movable between at least two positions; a splicing table having three rectangular aligned vacuum pads, a first pad being arranged on a stationary first block of a splicing table, and second and third pads being arranged on a second, pivotal block on the splicing table; an extraction member for withdrawing leader tape from the cassette; a cutting member for severing the leader tape and a length of magnetic tape; a splicing assembly for splicing the magnetic tape to the leader; and a winding device for winding the magnetic tape and leader after splicing. The cassette holder is pivotable about an axis between a first position straight above the splicing table, where it cooperates with the winding device, and a second position inclined to the splicing table which provides room for operation of the splicing assembly. The cassette holder pivots about an axis lying substantially in a plane through the second block pivotal axis, which plane bisects the width of the first vacuum pad between the pivotal axis of the second block and the upper surface of the first vacuum pad, the two pivotal axes being substantially parallel.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
367 words
An apparatus for filling a cassette with a length of magnetic tape, which cassette comprises two adjacent reels which are connected to a length of leader tape, which apparatus comprises: a cassette holder for holding the cassette to be filled, which cassette holder is movable between at least two positions, a splicing table for supporting a leading and a trailing end portion of the magnetic tape and for supporting the leader tape, which table is provided with three rectangular vacuum pads which are arranged aligned to each other, a first one of said vacuum pads being arranged on a stationary first block of the splicing table and a second and a third vacuum pad being arranged adjacent each other on a second block of the splicing table, which second block is pivotable about a block pivotal axis to bring the second or the third vacuum pad alternately in line with the first vacuum pad. an extraction member for drawing the length of leader tape wound around the reels out of the cassette and positioning the leader tape on the splicing table, a cutting member for cutting the leader tape into two parts and severing a length of magnetic tape having both a leading and a trailing end, a splicing assembly for resplicing the magnetic-tape leading and trailing end positioned on the splicing table to the ends of the parts of leader tape formed by the cutting member, and a winding member for winding the length of magnetic tape and leader tape into the cassette in cooperation with one of the reels, characterized in that the cassette holder is pivotable about a holder pivotal axis between a first position straight above the splicing table for cooperation with the winding member and a second position, in which it is inclined relative to the splicing table and in which the splicing assembly is operable, the holder pivotal axis is disposed at least substantially in a plane through the block pivotal axis, which plane bisects the width of the first vacuum pad, and the holder pivotal axis extends at least substantially parallel to the block pivotal axis between the block pivotal axis and the upper surface of the first vacuum pad.
Claim 2
Independent Claim
367 words
An apparatus for filling a cassette with a length of magnetic tape, which cassette comprises two adjacent reels which are connected to a length of leader tape, which apparatus comprises: a cassette holder for holding the cassette to be filled, which cassette holder is movable between at least two positions, a splicing table for supporting a leading and a trailing end portion of the magnetic tape and for supporting the leader tape, which table is provided with three rectangular vacuum pads which are arranged aligned to each other, a first one of said vacuum pads being arranged on a stationary first block of the splicing table and a second and a third vacuum pad being arranged adjacent each other on a second block of the splicing table, which second block is pivotable about a block pivotal axis to bring the second or the third vacuum pad alternately in line with the first vacuum pad. an extraction member for drawing the length of leader tape wound around the reels out of the cassette and positioning the leader tape on the splicing table, a cutting member for cutting the leader tape into two parts and severing a length of magnetic tape having both a leading and a trailing end, a splicing assembly for resplicing the magnetic-tape leading and trailing end positioned on the splicing table to the ends of the parts of leader tape formed by the cutting member, and a winding member for winding the length of magnetic tape and leader tape into the cassette in cooperation with one of the reels, characterized in that the cassette holder is pivotable about a holder pivotal axis between a first position straight above the splicing table for cooperation with the winding member and a second position, in which it is inclined relative to the splicing table and in which the splicing assembly is operable, the holder pivotal axis is disposed at least substantially in a plane through the block pivotal axis, which plane bisects the width of the first vacuum pad, and the holder pivotal axis extends at least substantially parallel to the block pivotal axis between the block pivotal axis and the upper surface of the first vacuum pad.
Claim 3
Dependent Claim
33 words
An apparatus as claimed in claim 1, characterized in that the holder axis is situated at substantially equal distances from the block pivotal axis and the upper surface of the first vacuum pad.
Claim 4
Dependent Claim
48 words
An apparatus as claimed in claim 1 or 2, characterized in that in the first position of the cassette holder said plane, in which the holder pivotal axis is situated, coincides with a plane of symmetry through the reel of the cassette which cooperates with the winding member.
Claim 5
Dependent Claim
