Abstract
Abstract A tape-splicing apparatus is provided with a pair of tape supply rolls with the tape being advanced from one roll through spaced clamping rolls to a point of use. The tape end from the other supply roll before a splicing operation is positioned against the other of the clamping rolls with the rolls being moved into clamping relationship in response to a tape end coming off an empty supply roll. A photoelectric cell senses the tape end and actuates a fluid motor to move the clamping rolls together and thus splice the tapes.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
141 words
In an apparatus for use in boxboard assembling for splicing adhesive tape to provide a continuous supply of the tape, the combination of a pair of rotatably mounted tape supply rolls means for continuously advancing a tape from one of said supply rolls, said means including a pair of clamping rolls normally spaced apart and movable into clamping relationship, the tape end of a full supply roll prior to splicing resting on one of said clamping rolls, and tape end responsive means located adjacent the path of each of the tapes between its roll and said clamping means and actuated by the end of a tape passing thereby and coming from an empty supply roll for moving said clamping rolls together into clamping relationship whereby the empty roll tape end is spliced to the tape end of a full supply roll.
Claim 2
Dependent Claim
141 words
In an apparatus for use in boxboard assembling for splicing adhesive tape to provide a continuous supply of the tape, the combination of a pair of rotatably mounted tape supply rolls means for continuously advancing a tape from one of said supply rolls, said means including a pair of clamping rolls normally spaced apart and movable into clamping relationship, the tape end of a full supply roll prior to splicing resting on one of said clamping rolls, and tape end responsive means located adjacent the path of each of the tapes between its roll and said clamping means and actuated by the end of a tape passing thereby and coming from an empty supply roll for moving said clamping rolls together into clamping relationship whereby the empty roll tape end is spliced to the tape end of a full supply roll.
Claim 3
Dependent Claim
35 words
In an apparatus as claimed in claim 1 with said clamping roll moving means comprising photoelectric cell means adjacent the paths of both of the tapes between the supply rolls thereof and the clamping rolls.
Claim 4
Dependent Claim
38 words
In an apparatus as claimed in claim 2 and comprising a fluid motor connected to said clamping rolls and actuated in response to the energization of one of said photoelectric cell means to move said clamping rolls together.
Claim 5
Dependent Claim
32 words
In an apparatus as claimed in claim 1 and comprising tensioning means responsive to a decrease in tension of either tape coming off of a supply roll for braking that supply roll.
Claim 6
Dependent Claim
43 words
In an apparatus as claimed in claim 4 with said braking means comprising a pivotally mounted tension arm for each supply roll and having an idler roller on the end thereof with the tape from that supply roll passing over said idler roller.
Claim 7
Dependent Claim
92 words
In an apparatus as claimed in claim 1 with said clamping rolls comprising a first pair of spaced rolls mounted in a fixed frame, a second pair of spaced rolls cooperating with said first pair of rolls, said second pair of rolls mounted in a frame having one end pivotally mounted so that the cooperating rolls at the pivotal end are in rolling engagement when a tape is passing therebetween, and means connected to said pivotally mounted frame for moving said frame into the clamping position in response to a tape end.
Claim 8
Dependent Claim
145 words
In an apparatus for splicing adhesive tape to provide a continuous supply of the tape, the combination of a pair of rotatably mounted tape supply rolls, means for continuously advancing a tape from one of said supply rolls, said means including a pair of clamping rolls normally spaced apart and movable into clamping relationship, the tape end of a full supply roll prior to splicing resting on one of said clamping rolls, means responsive to the end of a tape coming off an empty supply roll for moving said clamping rolls together into clamping relationship whereby the empty roll tape end is spliced to the tape end of a full supply roll, braking means for said supply rolls including a tensioning arm means, and means responsive to a decrease in tension of a tape coming off of a supply roll for braking that supply roll.
Claim 9
Dependent Claim
145 words
In an apparatus for splicing adhesive tape to provide a continuous supply of the tape, the combination of a pair of rotatably mounted tape supply rolls, means for continuously advancing a tape from one of said supply rolls, said means including a pair of clamping rolls normally spaced apart and movable into clamping relationship, the tape end of a full supply roll prior to splicing resting on one of said clamping rolls, means responsive to the end of a tape coming off an empty supply roll for moving said clamping rolls together into clamping relationship whereby the empty roll tape end is spliced to the tape end of a full supply roll, braking means for said supply rolls including a tensioning arm means, and means responsive to a decrease in tension of a tape coming off of a supply roll for braking that supply roll.
Claim 10
Dependent Claim
41 words
In an apparatus as claimed in claim 7 and wherein said Clamping rolls are moved in response to activation of photoelectrical means adjacent the paths of both of the tapes and located between the supply rolls thereof and said clamping rolls.
