6 Claims.
(01. 154-1)
This invention relates to apparatus for apply
ing decorative strips to sheet material, for exam
ple sheet rubber.
In the manufacture of articles of sheet rub
5 ber, such as bathing caps, bathing suits, and the
like, it is desirable to trim the articles with deco
rative borders. This may be accomplished most
satisfactorily by applying to the sheet material
design elements of sheet rubber of a contrasting
10 color.
The principal objects of this invention are to
rotatably mounted in pedestals 4|, 42 ?xed to the
base plate l0 and is driven by a sprocket 43 ?xed
to roll 13 through a chain 44 and a sprocket 45
?xed to shaft 40. The sprockets may be removed
and replaced by others to drive the cam shaft
at different ratios to the squeeze rolls. One or
provide e?iciency and economy in the production
of complicated design and to provide accuracy
of pattern.

Other objects will appear from the following
56 is mounted on a stud 51 or 58, adjustably
mounted in a slot 59 or 60, in either arm 48
or 49, so as to bear against the cams. Suitable
description and the accompanying drawing.
Of the drawing:
Fig. 1 is a plan view of a preferred form of the
invention with the work in place therein, parts
of the work being broken away.
Fig. 2 is a sectional elevation of the same taken
on line 2—-2 of Fig. 1.
,
Referring to the drawing, the numeral 410 des
ignates a base plate upon which are mounted a
pair of vertically slotted housings ll, [2 for ro
tatably supporting a pair of squeeze rolls I3, l4.
The lower roll 13 is mounted in boxes l5, I6
which rest in the slotted housings. The roll I4
is likewise rotatably mounted in boxes 11, I8 slid
more cams 46, 41 are ?xed to the cam shaft. An
equal number of arms, in the machine illustrated
two 48, 49, are pivotally mounted on studs 50,
5| adjustably mounted in slots 52, 53, in a sup 10
port 54 ?xed to base plate 10. A roller 55 or
resilient means, such ascoil spring 6|, having 15
the ends attached to the arms 48, 49, is provided
to hold the rollers against the cams. The arms
are preferably placed at different elevations so
as to pass each other during their movements.
Each arm is provided with a guide 62 or 63 at the 20
free end to guide one or more rubber strips.
The arrangement is such that each arm and its
strip guide is guided back and forth near the bite
of the rolls so that the strip or strips guided
thereby will enter the bite of the rolls and be 25,
laid on the sheet 28 in a sinuous path. Due to the
to exert pressure between the rolls. Rolls l3, 14
independent movements of the guides and the
placing of the arms at different elevations the
paths of the strips may overlap or cross each
30
other to form. pleasing designs.
The rolls l3, [4 pinch the strips against the
sheet 28 with sufficient force to permanently unite
the strips and the sheets. To aid in this pinch
have pinions 23, 24 ?xed thereto and meshing
ing action, one of the rolls may be knurled or
30 ably mounted in the same slots. Pressure screws
[9, 20 are threaded through caps 21, 22, ?xed to
the housings, and bear against the boxes 11, I8
35 with each other. A gear 25 is also ?xed to roll
l3 and meshes with a pinion 25a driven by any
convenient source of power, not shown, the ar
rangement being such that the rolls are driven
in unison.
7
For supporting the sheet material to be deco
rated, a shaft 26 is mounted in suitable hearings
on the housings ll, l2 and supports a roll 2‘!
of sheet material 28. The leading end of the
sheet is passed between rolls 13, I4 and may then
45 be carried from. the device by a conveyor belt 29
which passes around an idle roll 38' journaled in
40
housings ll, I2.
The strips of decorating material 3|, 32, 33,
34, which are of unvulcanized sheet rubber simi
50 lar to the material of sheet 28 but contrasting in
color thereto, are provided in coils 35, 3'6 sup
ported on rods 31, 38 in convenient relation to
the machine.
.
To provide for determinate guiding of the strips
55 to form an ornamental design, a cam shaft 40 is
milled to provide raised points or edges to locally 35
pinch the rubber together. By adjusting the cam
rollers and the arms supporting them, the throw
of the arms on their pivots may be altered.
I claim:
1. Apparatus for applying decorative strips of 40
sheet material, said apparatus comprising a pair
of pinch rolls, means for guiding a sheet‘ and a
plurality of strips of rubber superimposed there
on through the bite of said rolls, and means for
automatically and independently shifting the 45
path of each strip with relation to that of the
sheet as the sheet and strips are drawn through
the rolls.

2. Apparatus for applying decorative strips to
a sheet of material, said apparatus comprising 50
a pair of pinch rolls, means for feeding a sheet
of material through the rolls, and means for feed
ing a plurality of strips of rubber into superim
posed relation to the sheet as the sheet enters the
bite of the rolls, said last named feeding means in- 55

eluding means for laying the strips on the sheet
in-sinuous paths and in superimposed relation to
each other.
3. Apparatus for applying decorative strips to
a sheet of material, said apparatus comprising
a pair of pinch rolls, means for feeding a sheet
of material through the rolls, and means for feed
7 ing a'plurality of strips of rubber into superim
