A method is disclosed for repairing scratched glass bottles.
The scratches are filled with a suitable synthetic material which penetrates thereinto as a result of its low surface tension.
Description
~8Z3~1 In the course of time, returnable bottles are rendered un-attractive by scratches around the upper and lower edges of the cylindrical body of the bottle. Bottlers, to whom the appearance of a bottle is of great import-ance, segregate such bottles although they are other~ise perfectly satisfactory.
It is known to provide bottles with a coating of synthetic material, both for protection and for decorative purposes. The coating is in-tended to protect the glass from being scratched and to prevent the walls of the container from being weakened by scratching. The coating is furthermore to ~e such as ~ill withstand stresses arising from repeated re-use of the bottles. It is true that in this case the bottle itself is protected, but not the coating of synthetic material. Frequent re-use of the bottles renders the coating unsightly.
In order to extend the life of the bottle and retain its pleasing exterior, a special design of bottle has been proposed having a narrow, prajecting impact collar at the top and bottom of the cylindrical part thereof.
Although these collars become scratched in use, the scratches, being confined to t~o narro~ strips, do not render the bottle as unsightly as scratches dis-tributed over a large, unconfined area of the smooth surface of the bottle.
It is also known to apply soluble or decomposable coatings of synthetic materials to bottles by printing in a conventional cleaning lye. Such coatings are intended to be decorative and to replace labelling with printed foil or paper labels.
It is the purpose of the present invention to provide a way of achieving a longer life for bottles in danger of being scratched.
According to the invention, this purpose is achieved ~ith a method for repairing surface-damaged glass containers, more particularly scratch-ed glass. hottles, in that the depressions and/or scratches in -the surface-~23~
damaged area are filled ~ith a synthetic material which penetrates thereinto asa result of its lo~ surface--tension. This filling is preferably carried out in such a manner that at least the surface-damaged areas are covered with a thin ~up ~o 10 ~) film of synthetic material.
~ hereas in the case of known methods, the glass container has been protected from scratches by the coating of synthetic material, the invention follows a totally different path, in ~hat it accepts the scratches, but elimin-ates them ~ith a thin coating of synthetic material, thus restoring the pleasing exterior of the bottle. Since it is not intended to protect the bottle from scratches, but only to render the scratches invisible, the coating needed is relatively very thin. Nor is there any need for the synth tic material to be highly scratch-resistant, since the coating will preferably be renewed at each re-use. Although the ~ottle will normally be completely re-co~ted, local coating of areas su~jected to scratching is sufficient.
The dura~ility of ~he film of synthetic material applied to the bottle may be improved by applying the said film in a ~aterproof thickness. This reduces the danger of premature detachmen-t at the edges.
~ la~ever, since the film of synthetic material is porous, water may cause detachment over practically the whole surface. The danger of detach-nlent can in this case be reduced, of course, by using a suitably adhesivesynthetic material.
According to another development of the invention, the synthe-tic material used cannot be detached in water, but is soluble, detachable or decomposable in a cleaning lye. In this case the film is removed simultaneously ~ith the cleaning of the container, which is necessary in any event.
Satisfactory results have been obtained with a synthetic material ~hich hardens under ultra-violet radiation ~Z3~
In order to prevent the surface of the container from being rendered unsightly by handling after the synthetic material has been applied, the material used is preferably resistant to mechanical stresses such as impact and scratching. Ho~ever, as already indicated, the demands to be met need not be particularl~ high since the coating will preferably be renewed each time the bottle is recycled.
5ince the synthetic material will not, as a rule, be required to alter the appearance of the bottle, but only to render the scratches in-vi~ible, the material used ~ill be colourless or of the same colour as the con-tainer.
The coating of synthetic material may be applied in various uay~, for example by sublimation with a gaseous synthetic material condensing on the container, by spraying or rolling a liquid synthetic onto the container, by imm~xsing the container in a bath of liquid synthetic, or by pouring the synthetic over the container. Synthetic material in the form of a paste may also be applied by rolling or paintir.g.
Prior to the application of the synthetic material, the bottle Will be cleaned and dried, preferably under heat, so that the material may be applied to the ~hole surface, and ~ill be smooth and free from bubbles.
If the required thickness of syn~hetic material coating is not o~tained upon application, it may be adjusted by draining, blo~ing, doctoring or ~craping. After the coating has been applied and adjusted for thickness, it is preferably dried, more particularly by ultra-violet radiation.
An apparatus for carrying out the method is characterized by conveyor means ~hich move the containers individually through a plurality of consecutive treatment sections, the first comprising means for drying the sur-face of the bottle and the second a mechanism for applying the coating of synthe-

Satisfactory results have been obtained with a synthetic material ~hich hardens under ultra-violet radiation ~Z3~
In order to prevent the surface of the container from being rendered unsightly by handling after the synthetic material has been applied, the material used is preferably resistant to mechanical stresses such as impact and scratching. Ho~ever, as already indicated, the demands to be met need not be particularl~ high since the coating will preferably be renewed each time the bottle is recycled.
5ince the synthetic material will not, as a rule, be required to alter the appearance of the bottle, but only to render the scratches in-vi~ible, the material used ~ill be colourless or of the same colour as the con-tainer.

Synthetic material in the form of a paste may also be applied by rolling or paintir.g.
Prior to the application of the synthetic material, the bottle Will be cleaned and dried, preferably under heat, so that the material may be applied to the ~hole surface, and ~ill be smooth and free from bubbles.
If the required thickness of syn~hetic material coating is not o~tained upon application, it may be adjusted by draining, blo~ing, doctoring or ~craping. After the coating has been applied and adjusted for thickness, it is preferably dried, more particularly by ultra-violet radiation.
An apparatus for carrying out the method is characterized by conveyor means ~hich move the containers individually through a plurality of consecutive treatment sections, the first comprising means for drying the sur-face of the bottle and the second a mechanism for applying the coating of synthe-
2~
tic material. This second section may be follo~ed by a section comprising means for drying and hardening the coating.
The drying means in the first section is preferably in the form of air-nozzles. In order to eliminate any moisture remaining on the surface of the bottle to be coated, provision is made, according to one configuration of the apparatus, for heated rollers to be arranged at the end of the section, uponwhich the cylindrical containers roll.
~et container~ may be pre-dried particularly effectively by means of wipers applied to the surfaces thereof. This pre-drying is preferably carried out prior to the blo~-drying with air. Ths wipers are preferably leaf-shaped and are applied to the surface of the container in parallel with the axisof the c~lindrical container. Associated ~ith the containers is a drive which causes them to rotate about their own axes so that the whole surface i5 covered hy ~he ~ipers. The ~ipers and air nozzles may be arranged upon an inlet spider and may rotate there~ith.
The conveying means~ in the first treatment section may be in the form of conveyor worms followed by an inlet spider. A turntable ( a rotat-ing table ~ith pick-up locations for the containers at is periphery) may be used as a conveying means for the second treatment section.
In order that the containers may be coated on the move, ~he application mechanism is synchronized ~ith the movement of the containers, and may consist of a plurality of spray heads. In order to be able to apply the coating to the surface of the containers, each spray head comprises nozzles known per se ~hich can be pulsed on and off, the said nozzles being triggered individuall~ or in groups (Siemens ~eitschrift, 51st Year, Volume 4, April 77, pages 219-221). Each spray head may be in the form of a bar extending over the height of the container to be coated, a drive, more particularly a rotary head or plate, being associated with the container and causing it to rotate about its o~n axis, as a result of which the whole surface is coated. The spray head may also be in the form of a ring adapted to travel over the height of the container to ~e coated.
Instead of being sprayed, the synthetic material m~y ba rclled or pressed on. In this case, the application mechanism consists of a belt extend-ing along the treatment section. However, it is aiso possible to design the said application mechanism in the form of a labelling station, with moving rollers or segments applying the synthetic material to the containers.
The drying means arranged in the third section are preferably radiators, more particularly ultra-violet radiators.
The combination with a labelling machine is particularly satis-factory. In this case, no additional conve~ing means need be provided. Existing conveying means, especially thc turntable, convey the bottles to the labelling machine.
The invention is explained hereinafter in greater detail in conjunction ~ith the drawings attached hereto, l~herein:
Figure 1 is a diagrammatical plan vie~Y of an apparatus for repairing glass bottles;
Figure 2 is a plan view of an inlet spider;
~igure 3 is an axial section through the inlet spider according to ~igure 2;
~igures 4 to 7 sho~s various designs of applicatlon mechanism;
and Figure 8,on the same sheet as Figure 4, shows a drying and ~ardening unit.
A row of bottles 1, to be repaired, is fed on a plate conveyor 23~
belt 2 to a first treatment section. In the first part of this section, the feed means is in the form of a conveyor worm 3 which spaces the bottles apart.
The feed means in the second part of the first treatment section is in the form of an inlet spider 4 followed by a turntable 5, i.e. a rotating table having a plurality of bottle pick-up locations. The bottles leave the unit on an outlet spider 6 followed by a plate conveyor belt 7.
The basic design of this apparatus is known from bottling unitS. It is also known from these units that the bottles may stand upon turn-tables and may be gripped by heads which cause them to rotate about their own axes. This known design renders a detailed description unnecessary, especially since it i5 not essential to the method and apparatus according to the invention.
In the embodiment illustrated in Figure 1, a blowing box 8, 9 is arranged on each side of the conveyor section, from which air is blown from nozzles lQ,ll onto the bottles to be dried, after which the said bottles pass to inlet spider ~. The latter comprises a pluralitr or rotatable, heated rol-lers 12 ~Yith yielding surfaces upon which the bottles roll, supported externally b~ a guide 13. The bottles are thus heated and any residual moisture is removed from the surfaces thereof. This heating also ensures that no moisture condenses on the surfaces of the bottles before the synthetic material is applied.
Turntable 5 is arranged under a hood 14 to which air is supplied from blowing box 8. Volatile solvents from the synthetic coating n~terial leave the hood~ with the air supplied, through an outlet 15.
Means other than blowing boxes 8,9 and air nozzles 10,11 may be used for drying wet bottles. In t'ne embodiment according to Figures 2 and 3,a special inlet spider ~a is provided and comprises lower and upper pairs of supporting rollers 16,17 for the bottles. The said rollers pressing the bottles against an outer guide 18. As the spider rotates, the bottles rotate abou~
23~
their o~n axes. Associated ~ith each bottle pick-up location is a leaf-shaped ~iper 19 which wipes the liquid from the surface of the bottle. The bottles thus predried then pass into the range of air nozzles 20 which complete the drying operation. The said nozzles may be supplied with hot air to heat the bottles. This produces the same effect as heated rollers 12 mentioned herein-before.
After leaving the inlet spider, the bottles pass to second treatment section 21 equipped ~ith the application mechanism illustrated in Figures 4-7.
The mechanism according to Figure ~ comprises a plurality of flat spra~-heads 23 circulating on a closed track 22 along the path of travel o~ the bottles. The said spray-heads are synchronized with the movement of the bottle pick-up locations. Bottles 1, caused to rotate about their o~n axis by a turnta~le 26, kno~n per se, remain ~ithin the range of the spray-heads until each ~ottle has rotated through 360. Thq spra~-heads are connected, through a line 24 to a common supply 25 of synthetic material.
The application mechanism according to Figure 5 differs from that sho~n in Figure 4 in the matter of the spray-heads. Spray-heads 27 in Figure 5 are annular and are moved over the height of the bottles by a lifting c~linder 2~. As in the design according to Figure 4, the spray~heads may circulate on a closed stationary track, moving with the bottles along a part of their path of travel. It is also possible, ho~ever, to provide each bottle pick-up location with a spray-head. With annular spray-heads, there is no need for tKe bottles to rotate about their o~n axes.
In the design according to Figure 6, the application mechanism consists of a resilient belt 31 running over rollers 29,30, with the bottles 1 rolling on the said belt. As in the case of the gluing rollers in labelling ~23~
machines, the synthetic material is applied to belt 31 by an applicator-roller 32, the thickness of the coating being adjusted by scraper 33.
The design of the application mechanism according to Figure 7 ~orresponds largely to that of a labe~ g machine. Applicators 34, having curved surfaces are mounted to rotate or oscillate in a ro-tating carrier 35, and they roll on a roller 36 which is supplied ~ith synthatic material after the manner of a gluing roller. The said applicators, With their surfaces thus coated with synthetic material, then roll on bo-ttles 1, which rotate about their o~n axes, thus coating the said bottles. As is known from labelling machines, the whole surface of the bottle may be coated, with or withou~ relative move-ment bet~een the bottle and the surface of the applicator, by means of a non-uniform drive, appropriate curvature of the coated surface of the applicator, and an appropriate mounting. This produces a coating of uniform thickness.
The bottle, coated by one or the other of these mechanisms, then passes to third treatment section 37 on each side of which are arranged radiators 38 (Figure 8~, preferably ultra-violet radiators, for the purpose of dr~ing and hardening the coating of synthetic material. The length of this section depends upon the period of residence needed for drying.
As shown in Figure 1, turntable 5 also has a final treatment-section 39, in ~hich one or more conventional labelling machines 40 may bearranged.
