printed single or multiple layered textile articles.
Description
This invention relates to a method of and an apparatus for printing
both sides of single or multiple layer textile articles,
principally of articles wholly or partly consisting of man-made
fibers, by transfer printing sheets with the application of
pressure and heat.
The style of transfer printing one side of synthetic textile
fabrics and articles from prepared transfer sheets is a process
already known in the art. The process is carried out by placing a
sheet which has been provided with an impression of specially
prepared colored inks on the textile fabric that is to be printed,
and by then conducting the fabric and the transfer sheet in
combination between special calender rollers. One of the
two-cooperating rollers is heated. Between the rollers the inks on
the transfer sheet are transferred to the textile fabric by
sublimation.
It is the object of the present invention to provide a method as
well as apparatus which will permit both sides of a single or
multiple layer textile article to be simultaneously printed
efficiently in one operation.
The method according to the present invention for achieving this
object comprises the steps of covering both sides of a single or
multiple layer textile article with a transfer printing sheet,
conveying said article and said sheets between two relatively
spaced heated pressing platens, and closing the platens and thereby
simultaneously transferring impressions from said transfer printing
sheets to each side of said article.
This method permits both sides of a single or multilayered textile
article, primarily an article consisting wholly or partly of
synthetic fibers to be simultaneously printed in one operation. The
proposed method is therefore a substantial improvement on the
conventional method in which the two sides of a fabric were printed
in succession. Time is thus saved and the process is cheaper.
The present invention also concerns apparatus for performing the
above-described method. The proposed apparatus comprises two
separately heatable pressing platens forming a printing station and
adapted to be separately or jointly moved to close on each of a
continuous succession of textile articles which have been
previously provided on each side with a transfer printing sheet,
and means for intermittently feeding said textile articles between
said platens.
The proposed apparatus permits the method proposed by the invention
to be performed in an extremely efficient way. One advantage
consists in that a single machine comprising relatively simple
means can be used for simultaneously printing both sides of single
or multiple layer textile articles.
According to another feature of the invention a multilayer textile
article covered on each side with a transfer printing sheet may
first be drawn on a form. This will ensure that the textile article
retains its shape during the printing process.
According to yet another feature of the apparatus proposed by the
invention a feeding station may precede the printing station and a
conveyor belt made of high-temperature-resistant fabric may be
arranged to run in intermittent steps through both stations.
Moreover, a delivery station may follow the printing station and an
intermittently feeding conveyor belt made of
high-temperature-resistant fabric may be arranged to run through
the printing station and the delivery station. Both these
arrangements may be combined and the apparatus provided with a
feeding station preceding the printing station and a delivery
station following the same, the conveyor belt running through all
three stations. However, the printing station may be associated
either with only a preceding feeding station or conversely with
only a following delivery station, the conveyor belt travelling
through whichever two stations are employed.
The above features of the invention make a highly efficient
machine. This can be even further improved if, according to yet
another proposal, a reciprocating receiving table is also provided,
preferably of a kind that can be raised and lowered for
consecutively receiving the printed single or multiple layer
textile articles in a pile. Such a self-stacking receiving table
improves the efficiency of the machine inasmuch as it permits the
operating rate to be increased and an attendant at the delivery end
of the machine to be dispensed with.
An embodiment of the invention will now be described by way of
example and with reference to the accompanying schematic drawings,
in which:
FIG. 1 is a section through the apparatus for printing both sides
of a succession of textile articles conveyed through the apparatus
by an intermittently feeding conveyor belt;
FIG. 2 is a top plan view of a two-layer textile article (a
pullover) which has been drawn on a form and covered on each side
with a transfer printing sheet, and
FIG. 3 is a section taken on the line A--A in FIG. 2.
DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 1 shows an apparatus 30 (a platen press) for printing both
sides of textile articles 31, such as pullovers, which functions in
consecutive working steps. Substantially the machine comprises a
printing station 32 provided with printing tools, i.e., pressing
platens 33 and 34, a feeding station 35, a delivery station 36, a
conveyor belt 37 which runs in succession through all three
stations 35, 32 and 36 in the direction of the arrow 49 and a
self-stacking receiving table 38.
The conveyor belt 37 which consists of a high-temperature-resistant
woven fabric is endless and deflected over rollers 39. The drive
means of the conveyor belt are not shown since these are of
conventional kind. At the feeding station 35 and the delivery
station 36 tables 40 and 41 are located below the conveyor belt 37
for the purpose of supporting the belt. At least one of the two
pressing platens 33 and 34 which function as printing tools,
preferably the bottom platen 34, is padded, whereas the other which
in the drawing is the upper platen 33 is covered with a
high-temperature-resistant cloth 42.
At the feeding station 35 the textile articles 31 (pullovers) are
covered on each side with a transfer printing sheet 43 or 44.
However, with advantage the textile article 31 is first drawn over
a so-called form 45 (FIG. 3). The entire assembly 46, consisting of
the two transfer printing sheets 43 and 44 enclosing the textile
article 31 between them and possibly the form 45, is then placed on
the conveyor belt 37 which conveys it stepwise to the printing
station 32. When the assembly 46 has been thus fed between the open
pressing platens 33 and 34 at the printing station 32, the conveyor
belt 37 stops and the upper platen 33 is lowered into cooperation
with the bottom platen 34 by a hydraulic cylinder 47.
When the printing operation has been completed, the upper platen 33
is raised. The conveyor belt 37 advances and conveys the assembly
46 to the delivery station 36, where the assembly may either be
removed by attendant personnel or where it may remain on the
conveyor belt 37 to be delivered during the next step of the
conveyor belt 37 to the self-stacking receiving table 38. The
provision of a self-stacking table 38 which is adapted to be
reciprocated as indicated by the arrow 48 and which is fitted with
means for raising and lowering the table has the advantage that the
assembly 46 is automatically stacked in a pile and that fewer
operatives are thus required for working the machine.
The platen 33 may be forced down on the assembly 46 at modest or
high pressure -- as the circumstances may require.
