Let off roll 110, wind-up roll 210 realize accurate speed controlling.
General, slip shaft is made up of multiple differential slip rings, and when carrying out unwinding winding, differential slip ring is controlled can be with
Must moment values of trackslipping (moment of torsion) skid, slippage just compensates the speed difference of generation, it is possible to exactly
Control the tension force of each volume data, equal constant tension coiling, it is ensured that reeling quality.Above-mentioned sheet-fed printing material is cold
Scalding and save film unit, described let off roll 110 all uses slip shaft with wind-up roll 210, each on available slip shaft
Individual differential slip ring skidding principle, make let off roll 110 and wind-up roll 210 can rolling at least two volume cold stamping film 30,
Let off roll 110 with at least two volume cold stamping films 30 on wind-up roll 210 can unreel with equal identical tension or receive always
Volume.Volume has the let off roll 110 of at least two volume cold stamping films 30 and the rolling precision height of wind-up roll 210, it is possible to protect
The tension force of the film of at least two volume cold stamping films 30 on card let off roll 110 or wind-up roll 210 and flatness.Use
At least two the first haulage gear 120, each first haulage gear 120 can corresponding draw on let off roll 110
A volume cold stamping film 30.When described sheet-fed printing material cold wave province film unit carries out cold wave printing to leaflet,
The cold stamping film 30 of the whole breadth originally used can be divided into single multireel cold stamping film 30 and often roll up individually
Driving, often the row's pattern on the corresponding leaflet of volume cold stamping film 30, then can save when applying on leaflet
The part cold stamping film 30 that in the middle of originally and both sides are blank, it is possible to effectively save cold stamping film 30, save bauxite resource,
Reduce material cost.
Fig. 2, Fig. 3, Fig. 4 illustrate the leaflet of three kinds of patterns.Use above-mentioned sheet-fed printing material cold
When leaflet as shown in Figure 2 is printed by boiling hot province film unit, volume two cold stamping films 30 can be set to leaflet
Print;Use above-mentioned sheet-fed printing material cold wave to save film unit leaflet as shown in Figure 3 is printed
During brush, it is possible to volume two cold stamping films 30 are set leaflet is printed, and, only use the narrowest two cold
Scald film 30, it is possible to be greatly saved cold stamping film 30 material;Above-mentioned sheet-fed printing material cold wave is used to save film
When leaflet as shown in Figure 4 is printed by unit, volume 3 cold stamping films 30 can be set or only arrange one
Volume cold stamping film 30.Actual carry out cold wave printing time, can be the most specifically chosen, this enforcement
Sheet-fed printing material cold wave described in example saves film unit application flexibly, it is possible to effectively saves cold stamping film 30, save
Bauxite resource, reduces material cost.
In the present embodiment, the printed patterns of the corresponding row of the width ratio leaflet often rolling up described cold stamping film 30 is set
Wide 10-25mm, preferably 20mm, and then accurately can print often arranging pattern on leaflet, will not go out
Now print imperfect phenomenon, be unlikely to again to waste too many cold stamping film 30.Described cold stamping film 30 is set to volume two,
Described first haulage gear 120 correspondence is designed as two, can meet most actual printing operating mode, and single
Open printing material cold wave province film unit simple in construction, design is convenient, it is convenient to manufacture.
As it is shown in figure 1, described first haulage gear 120 include carry-over pinch rolls 122 and with described carry-over pinch rolls 122
