Claims.
This invention relates to wrapper banders for wrapping machines wherein a label band is attached to the main wrapper web by application of heat, its main object being to provide means 5` for automatically withdrawing the label band from contact with the heater, thus preventing `the band from being overheated while the feed of the wrapper web is interrupted.
This is accomplished by threading the lab i.) band-through arack back of the heater,'and from there onto the main wrapper web in' such a manner as to be swung clear of the heater lwhen the main wrapper drive stops. Whenever the wrapper reel stops, the band reel, dueto its inertia, delivers an amount of slack and, since the rack is pivoted above the heater and counterbalanced sufficiently to recover some of the slack between the rack and the band reel, it swings away from the heater, carrying with it the label I 2@ band 'and holding that position until the main wrapper drive starts.
The band rack can be made suiciently wide to accommodate a very wide band or two or more narrow bands arranged to run side by side.
In the accompanyingfdrawing which shows the application of this invention to the bander attachment of a bread wrapping machine operating to wrap the loaves' in waxed paper or similar materials,
3@ Fig. 1 is a sectional elevation showing how the label band is threaded through the release rack and onto the main wrapper web';
Fig. 2 is a cross-section on line 2-2 oi Fig. 1;
Fig. 3 is an end elevation of Fig. 1; and
Fig. 4 is a View showing a flnishedpackage having a band wrapper.
In carrying the invention into eiect there is provided a heater unit, means for intermittently feeding a continuous band over saidaheater 4unit 4c in contact therewith, and mechanism for automatically moving the band out oi contact -with said heater unit when its feed is interrupted. In the best constructions contemplated, said mechanism includes a pivoted rack adjacent said heater f unit, spaced bars on said rack adapted to guide the band into position to be pressed against said heater unit by the feeding tension applied to the band, and counter-weights on said rack for swinging it away from said heater unit with the band whenever the feeding tension is removed from the band, These various means and parts may be widely varied in construction for the particular device selected to ill 'strate the invention is but one of many possible concrete embodiments of the same. The invention, therefore, is not to (ci. 154-1) y f.
be restricted to the speciiic construction shown and described.
Referring to the drawing, Figs. 1 and 3, the band reel BR on shaft l2 is shown suspended Y from rods i3 and i4 of the machine by hangers 5 `I5 and iB. The heater unit il, Figs. 1 and 2, is shown mounted in arms i8 and i9 fast to shaft 20, which is journaled in hangers 2i and 22 suspendcd from rods I3 and l4 The heater unit Il consists of a flanged roller loosely mounted 1G on a cartridge type electric heater carried by arms I8 and i9 and connected yto an electrical supply circuit by wires passing through switch box SB, located ata convenient point on the machine. The material used for the label band i5 may be waxed paper, or any other suitable material.
Shaft 28 by 4means of crank 23 can be turned by shifting crank latch 23a from its position in hole 22a to hole 22h on quadrant 22e. By this 20 means the heater unit and the parts comprising the release mechanism may be swung out of the way for convenience in replacing a depleted wrapping material roll by a new roll.
The web feed for the wrapping material W, as 25 well as the loaf feed and wrapping mechanism, may be similar to those disclosed in Patent No. 1,926,245, granted Sept. 12, 1933, on the application of F. R. Schmitt, but with the heater unit ii for the label band located behind the roll of 3o wrapping material W, thus heat sealing the band B to the wrapping material W immediately as they contact on the roll WR.
The label band B is threaded over and in front of shaft 20 and hinge rod 25, Fig. 1, then to the Se rear of bars 25 and 21 in rack' 28 and between the flanges of the heated roller onto the wrapping material roll WR, where the heated band adheres to the web W and is carried along with it over the various rollers into the wrapping machine. 40
As long as the web W is being uncoiled from roll WR the band B is held in contact with heater I l, but if roll WR stops, the rack 28 is swung 50 into the dotted position 28' and the bars 26 and 2l thereof take up the slack B between shaft 2G and band reel BR and, in so doing, pull band B out of contact with heater il. The object oi this invention is thus automatically accomplished 55 and obviates` the necessity for any manual operation to prevent'overheating of the wrapper band.
What is claimed is:
1. The combination with a heater unit, of means for intermittently feeding a continuous band over said heater unit in contact therewith, and mechanism for automatically moving the band out of contact with said heater unit wheny its feed is interrupted. I
2. 'I'he combination with a heater unit, of means for intermittently feeding a continuous band over said heater unit in contact therewith, and mechanism for automatically moving the band out of contact with said heater unit when its feed is interrupted, said mechanism including a pivoted rack adjacent said heater unit, spaced bars on said rack adapted to guide the band into position to be pressed against said heater unit by the feeding tension applied to the band, and counter-weights on said rack for swinging it away from said heater unit with the band whenever the feeding tension is removed from the band.
3. The combination with a sealer unit, of means for feeding a continuous band over said sealer unit into Contact therewith, automatic mechanism' for relatively moving said band and sealer unit to separate them when the feed tension on the band is interrupted, mechanism for supporting a reel of wrapping material, band guiding means holding a portion of the band after the same has been acted upon by said sealer unit in contact with a portion of the wrapping material on the reel to seal the band to said material, and devices for guiding the united band and wrapping material from the reel toward a wrapping position.
dering said band adhesive, of means for feeding under tension a continuous band over said unit in contact therewith, and mechanism for automatically moving the band out of contact with said sealer unit when said tension is relieved, said 10 mechanism including an element contacting the lband adjacent said unit, and devices vyieldingly supporting said element to urge the band out of contact with the sealing unit with a force insumcient to overcome feeding' tension of the band 15 whereby when the band is under tension it contacts the sealing unit against the action of said devices and when the tension is released the band is automatically moved out of contact with the sealingv unit. 20
