As used herein, term " film " generally is used for describing any thin flaky material with a plurality of layers, and at least one in these layers is deposited on parts.Described sedimentary deposit can be protectiveness, decorative coating etc.Metal, color, label, labeling, printed article, plastics and many other materials can be applied to parts of the present invention by film.Illustrate and be described in following patent applicable to exemplary film of the present invention: for example, the U.S. Patent application of authorizing the people such as Meiki of announcing on November 19th, 2009 is announced at March 13 in 2009/0286054,2008 authorizes the people's such as Colella U.S. Patent application 2008/0063863 and the United States Patent (USP) of authorizing Bethune 7 of announcing on August 12nd, 2008,410,551.

Although for different final results can be used different films, typical film will comprise carrier, discharge compound, sedimentary deposit and adhesive.Carrier keeps the layer that will deposit, and after deposition, carrier can be recovered, and for example by the film recover, is obtained.Carrier is usually for tolerating heat, pressure or both thin plastic sheets or other cheap material sheet of described deposition process.Discharge compound and be generally liquid, gel or semisolid material, it allows carrier easily from sedimentary deposit, to pull open and do not take any sedimentary deposit out of.Preferably, it is volatile discharging compound, makes when carrier is opened, and discharges compound and evaporates simply.Alternatively, nonvolatile release compound can be washed off or be wiped in post-depositional step.

Sedimentary deposit can be the material of any number and himself can comprise a plurality of layers.Thin vacuum metallization processes metal level is for decorating and protect both a kind of popular selections.Usually color layers will be added to this metal level.Metal film also can produce by other method, and as expected result desired become like that thick or thin.Obviously, thinner sedimentary deposit will be more economical and be had larger pliability, but thicker layer will be more durable and demonstrates less misalignment when depositing.Finally, adhesive is used for sedimentary deposit is attached to parts simply.Adhesive is well known in the art, and they can be activated by temperature, pressure and activating compounds or all these.In the situation of epoxides that formalizes the soonest, parts can be coated with a kind of chemical constituent of epoxides, and another kind of chemical constituent is on film.When the film contact component, react and form adhesive phase.In most of the cases, adhesive is activated by the pressure between mandrel and parts and/or heat simply.In case of necessity, the carrier side of film contacts with mandrel, and the sedimentary deposit side of adhesive and film contacts with parts.

Forward now Fig. 3 to, it shows existing paper tinsel coining manipulation to highlight difference of the present invention and advantage.There is the rotatable mandrel 60 that is attached to mandrel clamper 61 in Fig. 3.Parts 63 are shown as by member holder 66 and remain on appropriate location.Parts 63 have smooth sidewall 65, and described sidewall rotates on the direction contrary with mandrel 60.Film 62 is fed between the smooth sidewall 65 of mandrel 60 and parts 63 and both contact with them.Such as can be seen, the angle between mandrel 60 and parts 63 never changes.This allows film 62 only laterally to move and be not twisted all the time or be forced to shift out outside a plane of movement.This configuration applies the minimum stress to nothing to film, and generally causes good coverage rate.Known this system also is applicable to symmetrical frustum conic section.Yet this too simple system is not suitable for the parts with asymmetric edge.

Fig. 4 shows the schematic diagram according to the equipment of the parts that comprise asymmetric edge for coating of the present invention.Equipment 69 has mandrel 70, and described mandrel rotates and is attached to mandrel clamper 71.Member holder 76 keeps having the parts 73 at asymmetric edge 80.Film 72 is arranged between mandrel 70 and parts 73.Parts 73 rotate on the direction contrary with mandrel 70.As will be further detailed, the one or both in mandrel 70 and member holder 76 all moves with another angled relation.In Fig. 4, member holder 76 is placed on plate 81, and described plate is attached to mandrel clamper 71 via hinge 82.This is only a kind of mode that realizes the angular movement of necessity of the present invention.Mandrel and member holder are without being connected, such as skilled in the art will appreciate, angular movement can carry out Long-distance Control by computer, described computer with pre-programmed mode control assembly clamper, mandrel or they both, such as controlling with servo motor, air motor etc.

Being applicable to mandrel of the present invention can be the conical shape of frustum and (sees for example mandrel 69, Fig. 4), cylindrically (see for example mandrel 102, Fig. 5) or other symmetrical shape roughly.Equally, mandrel can be firm or deformable.So-called deformable, refer to that mandrel can conform to irregularly shaped, for example recessed or protruding.Deformable mandrel will be used for applying respectively for example the first angled edge 34 and the second angled edge 36 of parts 32, see Fig. 2.Deformable mandrel is useful following the time: when coating has the parts of mark projection or that lower, for example, when name of product, trade mark or logo directly being molded onto in the parts that will decorate.

The slightly more detailed schematic diagram that Fig. 5 is equipment 90 of the present invention.Parts 92 are shown having asymmetric edge 94, sidewall 96 and top 98, and are attached to member holder 100.Mandrel 102 is shown as and is attached to mandrel clamper 104, and also shows mandrel heater 106.Use mandrel heater 106 when the adhesive phase of film during by thermal activation, but this is unwanted to contact adhesive, epoxides etc.Film 108 is illustrated and is attached to film distributor 110 and film recover 112.Film 108 is shown as roller, but, in its simplest form, film 108 has the first edge 114 that is attached to film distributor 110 and the second edge 116 that is attached to film recover 112.As shown in the figure,

mandrel

102 and 104 rotations of mandrel clamper, and parts 92 and member holder 100 are rotated in the opposite direction.Film distributor 110 and film recover 112 are also rotatable so that film 108 is fed between mandrel 102 and parts 92.Film distributor 110 and film recover 112 rotate serially or they only can rotate between the processing of each parts, i.e. index.In addition, also can by new Disk-loaded waveguide between film distributor 110 and film recover 112 with for processing each parts, film distributor 110 and film recover 112 are without rotation in this case.

As shown in Figure 5, film distributor 110 and film recover 112 should have the free degree moved around axis 111 and 113.If they only move left and right or only move up and down around

axis

111 and 113, this motion is considered to two dimensional motion.If they can move up and down and move left and right around

axis

111 and 113 simultaneously, this motion is three-dimensional motion.Do not want to be subject to the constraint of any theory, be known that when the angle at asymmetric edge around change around parts and member holder (or mandrel, or both) while being moved to proofread and correct this variation of angle, film is subject to the effect of stress.When apply smooth parts or even during the frustum conic section without undergoing this stress, because the angle between film, mandrel and parts never changes.

As used herein, " moving collaboratively " is intended to mean at least one the mobile angle with explanation mandrel and the variation of the parts with asymmetric edge on two dimension in film distributor or film recover.Preferably, film distributor and film recover all move on two dimension, and more preferably at least one in mulch film distributor or film recover moves on three-dimensional, and even more preferably mulch film distributor and film recover all move on three-dimensional.At film, apply in process, how film distributor and film recover move to alleviate the geometry that will depend on all parts to the stress of film.Should be appreciated that the intent of the present invention and purpose are to process the parts that have as lower limb, the angle at described edge applies in process and changes at least one times at film, but the number of times of the degree changed and change will be different because of parts.Yet, as rule, this equipment keeps the surf zone of mandrel to be roughly parallel to the edge of coated parts, and feed best film and make its appropriateness flatly enter into the space between mandrel and parts, that is, twisting does not occur.Equally, if film by index (not fed continuously), it still can be handled to keep it to become general planar and parallel relation with the edge-of-part interface with mandrel.Use this general rule, those skilled in the art can be programmed to coordinate to film distributor, film recover or both motions the configuration of each nonsymmetrical component.The movement technique of mechanical device such as film distributor of the present invention and film recover will be known to those skilled in the art.Useful air motor, servo motor etc. come moving film distributor and film recover, the caused motion of angle of the controller tunable mandrel that simultaneous computer is auxiliary and the variation of member holder.
