Abstract
A linking element for use in conjunction with silk screening. The linking element, which includes apparatus enabling securement to the screening fabric, is attached to a strip of fabric to be secured to the stretching frame, enabling the use of a smaller screening fabric and more control over the tension. The element may be used in tandem.
Description
- This invention relates to the art of silkscreen application, and in particular, a method for and apparatus enabling the extended life of a silkscreen, while allowing a more uniform tension thereon during use, resulting in a superior end product.
- Use of silkscreening to transfer colors and/or patterns to wearing apparel and other objects is well known and has been utilized for a long period of time. The art of silkscreening and the mechanisms for facilitating the silk screening have evolved and improved over the years, but the one constant is the screen itself, which also has improved, which must be fabricated of a flexible, strong, durable, fine mesh fabric, and therefore, becomes quite expensive. It has, therefore, become imperative that the amount of silkscreen material that is wasted be kept to a minimum, and further, that the screen be capable of being used many times.
- It is with the increasing need for efficiency in mind that screens are primarily used on retensionable frames that allow multiple use of the screen and thus have become standard, but even though the frame has many improvements over the former expandable frames utilizing rectangular cross-section elements, the screen still tends to wear at the portion where the fabric is tensioned over the frame element itself.
- It is with the prior art in mind that the present invention provides a means and method for securing a more uniform tension on the screen during the printing process, but also provides the opportunity of utilizing a stronger, more coarse material, where the material actually contacts the frame, increasing the life of the screen.
- It is another feature of the present invention that through the utilization of an interlocking member allowing the end-to-end or side-to-side splicing of a fine mesh screen to a more economical material to allow the use of a smaller piece of the more expensive screen, and yet accomplish the desired results.
- The utilization of a smaller piece of screen material results in less material to stretch which requires less “stretch time” and therefore a quicker stabilization and earlier use.
- Another feature of the present invention creates, through the utilization of one or more screen extensions, the ability to place greater tension upon the screen material.
- Still another feature of the present invention is a more stable screen printing mesh.
- Yet another feature of the present invention is the ability to utilize a greater percentage of the screen print area.
- The use of the extension facilitates the movement of the pre-softening pocket outwardly freeing up more of the actual screen area for use enabling larger prints and facilitates the actual coating process.

FIG. 1 is a plan view of the tandem screen extender in place on a retensionable screen frame. -
FIG. 2 is an isometric view of the interconnection between the silkscreen and the tandem extender bar and extender screen. -
FIG. 3 is a sectional view along lines 3-3 ofFIG. 2 . -
FIG. 4 is a sectional view showing the inventive extender as used on one form of the tensionable frame. -
FIG. 5 is a sectional view showing the extender bar and extender tandem as shown on a second form of retensionable roller frame. -
FIG. 6 is a plan view utilizing the tandem system in conjunction with a second extender. - As seen in
FIG. 1 , a rectangularsilk screen panel 2 is secured to interconnecting or splicingmembers 4 along the majority of each of its edges, and the interconnecting splicing ortandem members 4 is likewise connected toextender mesh strips 6, which are then, as explained hereinafter, each attached to one of thelinear elements 8 of the retensionable frame. Each of theside elements 8 are interconnected by a rigid corner member 10, and as known in the prior art, a tensioning element, judiciously applied to theside members 8, allows the appropriate tension to be placed uponsilkscreen member 2. - Reference is now had to
FIG. 2 , wherein it can be seen that thescreen mesh 2 is secured to thetandem unit 4 by being secured by aspline element 12, which as explained hereinafter, is locked into thetandem unit 4. Theextender mesh 6 likewise is secured to aspline member 14 and again, as explained hereinafter, is locked intomember 4. The exterior or opposite edge ofextender unit 6 is likewise secured to aspline 16, which is subsequently secured to the retensionable frame member. - Reference is now had to
FIG. 3 , wherein it can be seen that thetandem unit 4 is a wide block-shaped W in cross-section with verticalexterior legs interior leg 22, such that thefabric 2 is wrapped aroundspline member 12, which is then captured in aprotective locking element 24, including a second protruding lip 26, which is snapped beneath the protrusion of T-shaped center leg 22. Likewise theextender mesh 6 is wrapped aroundspline member 14, which is then snapped into the opposite side oftandem 4 and locked in place beneath the opposite lip of the T-shaped center leg 22. - As stated hereinabove,
FIGS. 4 and 5 depict two distinct retensionable frame members; the one shown inFIG. 4 includes tubular sides which are kept from bowing by arigid supports 30 which lie inside theroller tension element 32 to which theextender 6 is secured.Extender 6 is attached to thespline member 34, which is very similar tospline member 14, described hereinabove.FIG. 5 depicts a similar attachment to a retensionable frame, wherein theroller 36 does not have a support member, but the screen may be cut to accommodate any bowing. - Reference is now had to
FIG. 6 which is similar toFIG. 1 and identical numbers will identify identical elements. It is to be noted, however, that in this particular depiction,extender member 6 is actually secured to asecond spline 16 to secure the structure to another tandem element, allowing adaisy chain extender 38 which is then secured to theframe element 8. This particular configuration allows increased tension upon large screens by allowing the tension to be originally applied throughextender member 6 and then removingextender 38 once a predetermined extended size is reached and securingspline 16 directly to theroller 8 and applying further tension. It is to be understood that in certain circumstances more than one extender could be used depending upon the relative size of the screen and frame. Further, when greater tension is required a series of extenders may be used, sequentially removing them as the screen expands (the screens do not quickly return to size) until the desired tension is reached. It is the overall goal that the actual silkscreen never contacts the frame. - In addition to the advantages mentioned hereinabove, it is to be noted that the pre-softening of the corner can actually occur in the
screen 2 itself or can in fact be accomplished by havingsplines 4 be shorter than the relative side of thefabric 2, allowing the pre-softening to occur in theextender mesh 6. - Further, the tandem stretching bar prevents overtensioning or breaking the silk screen fabric by physically intervening or interrupting the process when it contacts the stretching frame.
- The membrane and screen printing frame connector bar can be preshaped with presoftened corner bands and deflection compensation to accept non-tailored screen printing mesh.
- Thus, as can be seen, the present invention gives the silkscreen handler a method and apparatus for greatly reducing the amount of fabric used, stabilizing the fabric during use and further extends the life of the fabric.
