I claim:
1. In a tape dispensing assembly comprising ‘a base ma
arcuate panel 250, FIGS. 1 and 2 and shown separately 25
in FIG. 4. Such switch panel comprises a plate body

a support thereon for a supply roll of tape,

formed with vertical ?anges such as 253, 254 for anchor

At the vappropriate locations lengthwise of the arcuate
plate 250, such ‘as to afford the above described location
for the respective switch, the plate is apertured for re

Assuming the “red” and “blue” selectors 60d and 60
respectively set for the desired two different tape lengths,
automatic feed, moistening, cut-off and delivery of the
shorter tape length is had by manual closure of the “red”
cycle-starter switch 7425. When the rotary measuring pro
jection 46 comes opposite and engages the actuator roll 55
622, see FIG. 3, of the “red” varm trip switch 629, said
normally closed switch is thereby opened and the feed
cycle halted by deenergizing of the actuator solenoid 15,
with stopping of the motor and return of the holding
switch 150 to normal open position vattendant on the cut 60

16 to normal released position.
Delivery of the selected longer tape length is had by
operator closure of the “blue” cycle-starter switch '75}.
‘The norm-ally open relay switch 626 is thereby closed, 65
along with the holding switch 156, and through the illus
trated relay circuits and lead connections through the
junction box 300 the “red” trip switch 620is in effect
shunted out or cancelled from the then ‘active circuits. 70
Hence the movement of the driven measuring projection
46 past the “red” trip switch 629 although engaging and
moving the switch actuator roll s22 has no cycle-halting
effect thereat and the feed cycle continues on until said
