Abstract
Abstract In order to prepare stained glass chips so that they can be assembled together into a stained glass window or other work, the edges of the chips are wrapped with foil. This foil is dispensed from a roll along a path to a wrapping roller. The roller has a groove with a step and defines portions of different widths to accommodate stained glass chips and foil of different widths. The size of the groove portions are wider than the chips so that the foil will wrap around the edges of the chip and be pushed into contact with the side of the chip lying adjacent to its edges when the chip is pressed against the groove portions. Rotation of the chip also rotates the wrapping roller which is mounted so as to be free to rotate. This pulls the foil being applied to the chip.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
197 words
Apparatus for dispensing and wrapping foil about the edges of glass chips and the like, said apparatus comprising a frame, means mounted on said frame for supporting a roll of self-adhering foil with the roll being rotatable as the foil is withdrawn therefrom, and a wrapping roller for receiving said foil from said roll with the self adhering face of said foil facing upwardly, said roller having a peripheral groove, said groove having steps on opposite sides thereof with the groove having a first portion thereof above the step wider than a second portion thereof below the step, one of said portions having a width narrower than the width of the foil, means mounted on said frame for supporting said roller with said roller being free to rotate as one of said chips is received within said groove within at least one of said portions and presses to said foil against the sides of said one of said portions within which it is received and one of the bottom of said groove and said steps while turning said chip to simultaneously withdraw said tape from said roll and wrap said foil about the edges of said chip.
Claim 2
Dependent Claim
197 words
Apparatus for dispensing and wrapping foil about the edges of glass chips and the like, said apparatus comprising a frame, means mounted on said frame for supporting a roll of self-adhering foil with the roll being rotatable as the foil is withdrawn therefrom, and a wrapping roller for receiving said foil from said roll with the self adhering face of said foil facing upwardly, said roller having a peripheral groove, said groove having steps on opposite sides thereof with the groove having a first portion thereof above the step wider than a second portion thereof below the step, one of said portions having a width narrower than the width of the foil, means mounted on said frame for supporting said roller with said roller being free to rotate as one of said chips is received within said groove within at least one of said portions and presses to said foil against the sides of said one of said portions within which it is received and one of the bottom of said groove and said steps while turning said chip to simultaneously withdraw said tape from said roll and wrap said foil about the edges of said chip.
Claim 3
Dependent Claim
109 words
The invention as set forth in claim 1 wherein said groove has a plurality of said steps, said steps being of successively smaller diameter in a direction inwardly of said roller, said steps defining a plurality of portions of widths which are successively narrower inwardly of said roller, with the one of said steps of largest diameter having said first portion thereabove and said second portion therebelow, said steps being adapted to receive foil of successively narrower widths and each of said portions being adapted to receive chips of successively narrower width whereby to provide for the wrapping of the foil about different chips having a plurality of widths.
Claim 4
Dependent Claim
93 words
The invention as set forth in claim 2 wherein a pair of said roll mounting means is provided for supporting a pair of said rolls on opposite sides of said frame, a pair of said rollers also being provided, said rollers each having a groove and steps with the groove and steps in one of said rollers providing portions of different width than the groove and step in the other of said rollers, said rollers also being mounted on opposite sides of said frame for receiving foil and chips of different widths therein.
Claim 5
Dependent Claim

The invention as set forth in claim 4 wherein said back tension applying means is a friction clutch.
Claim 7
Dependent Claim
45 words
The invention as set forth in claim 1 wherein said foil is adapted to have a backing strip on the adhering face thereof, and a stripper bar mounted on said frame between said roller and said roll for separating said backing strip from said foil.
Claim 8
Dependent Claim
33 words
The invention as set forth in claim 6 further comprising foil guide means mounted on said frame between said stripper and said roll for defining a path for said foil into said stripper.
Claim 9
Dependent Claim
