Abstract
Abstract An improved pressure pad attached to a plunger mechanism of a splicer utilized on an automatic cassette tape loading machine. The pad has a multiplicity of intersecting slots in its bottom surface and at least one aperture penetrating its thickness. The aperture is connected to a vacuum passageway so as to provide communication between the slots and a vacuum source. The slots provide even distribution of a suction force to the splicing tape as it is applied to the tapes to be spliced.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
176 words
In combination with a splicing tape dispenser-applicator mechanism comprising: means for feeding an elongate splicing tape, guide means for positioning the leading end of said tape as it is advanced by said tape feeding means, cutting means for severing a length of said tape including the leading end thereof at a selected point relative to said guide means, and means for dispensing said length of tape severed by said cutting means comprising (1) a plunger disposed within a guide channel, (2) means for releasably holding said severed length of tape against the bottom surface of said plunger, and (3) a pressure member attached to said plunger bottom surface for pressing said severed length of tape onto materials to be spliced, the improvement comprising an improved pressure member in the form of a resilient pad having a multiplicity of intersecting cuts so as to form a reticulated bottom surface, said pad having one or more apertures through its thickness to provide pressure communication between said cuts and one or more corresponding vacuum source passageways within said plunger.
Claim 2
Dependent Claim
176 words
In combination with a splicing tape dispenser-applicator mechanism comprising: means for feeding an elongate splicing tape, guide means for positioning the leading end of said tape as it is advanced by said tape feeding means, cutting means for severing a length of said tape including the leading end thereof at a selected point relative to said guide means, and means for dispensing said length of tape severed by said cutting means comprising (1) a plunger disposed within a guide channel, (2) means for releasably holding said severed length of tape against the bottom surface of said plunger, and (3) a pressure member attached to said plunger bottom surface for pressing said severed length of tape onto materials to be spliced, the improvement comprising an improved pressure member in the form of a resilient pad having a multiplicity of intersecting cuts so as to form a reticulated bottom surface, said pad having one or more apertures through its thickness to provide pressure communication between said cuts and one or more corresponding vacuum source passageways within said plunger.
Claim 3
Dependent Claim
245 words
In combination with a machine for loading a selected supply tape into a cassette which includes a tape leader, said machine having a splicing block assembly for supporting the leading end of the supply tape and the leader of the cassette to be loaded, and improved splicing means for splicing a section of said leader and said supply tape together, said improved splicing means comprising in combination: means for feeding an elongate splicing tape; tape feed operating means for operating said tape feed means so that a predetermined amount of tape is advanced by said tape feeding means; guide means for positioning the leading end of said tape as it is advanced by said tape feeding means; cutting means for severing a length of said tape including the leading end thereof at a selected point relative to said guide means; a plunger guide channel; means for dispensing said severed length of tape comprising a plunger disposed within said guide channel; means for releasably holding said severed length of tape against the bottom surface of said plunger; and a pressure member attached to said plunger bottom surface for forcing said severed length of tape onto materials to be spliced, said pressure member comprising a resilient pad having a bottom surface characterized by criss-crossed slots penetrating perpendicular to said surface, said pad having one or more apertures through its thickness to provide vacuum communication between said slots and one or more corresponding vacuum passageways within said plunger.
Claim 4
Dependent Claim
245 words
In combination with a machine for loading a selected supply tape into a cassette which includes a tape leader, said machine having a splicing block assembly for supporting the leading end of the supply tape and the leader of the cassette to be loaded, and improved splicing means for splicing a section of said leader and said supply tape together, said improved splicing means comprising in combination: means for feeding an elongate splicing tape; tape feed operating means for operating said tape feed means so that a predetermined amount of tape is advanced by said tape feeding means; guide means for positioning the leading end of said tape as it is advanced by said tape feeding means; cutting means for severing a length of said tape including the leading end thereof at a selected point relative to said guide means; a plunger guide channel; means for dispensing said severed length of tape comprising a plunger disposed within said guide channel; means for releasably holding said severed length of tape against the bottom surface of said plunger; and a pressure member attached to said plunger bottom surface for forcing said severed length of tape onto materials to be spliced, said pressure member comprising a resilient pad having a bottom surface characterized by criss-crossed slots penetrating perpendicular to said surface, said pad having one or more apertures through its thickness to provide vacuum communication between said slots and one or more corresponding vacuum passageways within said plunger.
Claim 5
Dependent Claim
17 words
Improved splicing means according to claim 2, wherein said slots have a width of about 0.2 millimeters.
Claim 6
Dependent Claim
23 words
Improved splicing means according to claim 3, wherein said slots form a regular orthogonally-intersecting pattern on said bottom surface of said pressure pad.
Claim 7
Dependent Claim
20 words
Improved splicing means according to claim 4, wherein parallel slots of said orthogonally-intersecting slots are separated by about 0.5 millimeters.
