Abstract

A hand-held tape applicator for foam tapes is described. The tape applicator can be made to accommodate tapes of various thicknesses, including foam tapes in a range from about 0.3 mm to about 3 mm thick. An application face (which contact directly with the tape) has a small angle and minimizes risk of removing a protective film from the tape during application. An optimal adhesion of the tape can be obtained in a one-step manual application process, without requiring an operator to apply pressure in a separate step.

Hand-Held Tape Applicator for Foam Tapes of Various Thicknesses

Operators who need to repeatedly apply foam tapes (e.g., in structural glazing) sometimes

use a hand-held tape applicator (e.g., the tape applicator “TA1” shown in FIG. 1). The tape

applicator helps to hold the foam tape in the correct position, and facilitates correct application

and performance of the foam tape due to full contact of tape with bonded surface. In the case of a

transparent tape material, the tape can also be applied with minimal entrapment of air bubbles,

thereby improving the appearance of the tape.

Such a small and simple hand-held tape applicator device makes the application of foam

tape a very easy and fast process. It is easy to keep, transport, and handle the tape applicator, and

the results of tape application (e.g., production speed and quality) are about the same as when large

and heavy mechanical or pneumatic devices are used.

Considering FIG. 1, tape applicator TA1 includes a handle/grip portion H1, guide portions

G1 and G2, and a channel C1. Channel C1 has a width W1 (defined by spacing of G1 and G2)

and a depth D1 (defined primarily by G1). For TA1, depth D1 is essentially constant along the

length of channel C1. D1 is selected to accommodate a particular thickness of tape. G2 is shown

as being taller than G1. G2 typically serves as a guide along an edge of a substrate (e.g., a panel)

to which the tape is being applied, to enable a consistent application of the tape close to the edge

of the substrate.

A tape applicator of the type TA1 has some significant limitations – for example, the tape

width and thickness are limited by width W1 and depth D1 of channel C1. If an operator needs to

use tapes of various widths and thicknesses, multiple applicators would be needed, with

dimensions selected for each tape. It could be desirable to at least accommodate a range of tape

thicknesses, for a given width of tape.

For example, consider a production facility needing to bond various panels to frames for

making façade cladding; depending on the panel size, material and coefficient of thermal

expansion differences, th...
