lie it known that 1. Join lVLicL-iURIN, a subject of the King of llngland. residing at lirookficld. in the county of Worcester and State of hi: 'sachusel'ts, have invented certain new a2 l useful improvements in Processes oi Tenet-ring; and i do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to veneering and more particularly to the formation of a tape in which the paper or cloth backing may be easily removed from the gummed face thereof.

It has for an object to provide a gummed tape in which a film of material is inserted between the tape and the film of gum carried thereby to permit the tape being readily detached from the gummed portion thereof, after said gummed portion has been applied.

A further object of this invention is to provide a veneer tape having a film of material interposed between the tape and film of gum carried thereby, to permit the paper being readily removed. after said tape has been applied and in having the central film or material of such a character as to cause said central film to adhere either to the film of gum or tape as desired.

Further objects will be apparent from the following specification,appended claims and drawings, in which Figure 1 is a perspective view of a portion of the veneer tape snowing the composite elements thereof,

Fig. 2 is a similar view showing the veneer tape applied and the tape proper as partly removed, and

3 is a sectional view showing the tape applied, but this view shows the interposed film material as being removed from the gummed face with the paper.

in veneer-lug tape of this class, it is understood that in joining the meeting edges of'pieces of veneer, a gummed tape is placed over the meeting edges and this tape may subsequently be removed as by sand papering or other means common to the art of veneering. The tape referred to in this invention is for application in the usual manner and it may be gummed so that only the application of moisture is necessary for applying the tape or the treated .t'ape may be furnished to. receive the glue or other adhesive to be applied in the application of the tape. After the tape has been applied to the meeting edges of pieces of veneer and the adhesive has had time to harden, the tape may be easily removed from the film of adhesive so that in finish ing the work, it is only necessary to remove the film of adhesive which as will be appreciate-d, means a great saving in efiort and time. The tape will support the gummed face during its application and through the gummed face will hold the edges of the pieces of veneer until the adhesive has set, but the degree of adhesion between the tape and the gummed iace such as to permit the removal of the tape when desired.

Referring to the drawings, 10 indicates a tape which may be of paper or cloth as desired. and this tape may support a film of adhesive 11. The tape 16 is treated with a film of material 12 to prevent the gummed face. 11 from penetrating the pores or fibers of the tape so that through the inserted film of material 12, a line of separation between the tape 10 and gummed face 1]. may be had.

Fig. 1 shows the completed tape which requires only moistening of the film of adhesive for application, but it is understood that this film of adhesive may be added to the tape immediately before the tape is applied or a tape with the film of material indicated at 12 may be applied to a surface which is supplied with the equivalent of the adhesive con'iprising the film 11.

Fig. 2 shows a. section of tape applied to.

the meeting edges of sections of veneer 13 and it is assumed that the gummed face has sufiiciently set or hardened to permit the removal of the tape 10. in this instance, the composition of the film of material 12 is such, that it' has a greater atiinity for the gummed face 11 than for the tape 10 so that when the tape 10 is being removed as suggested in Fig. 2, the film 12 remains on the filmof adhesive 11. 7

Fig. 3 shows the film 12 being removed with the tape 10 and in this instance, the composition of the film 12 has a greater affinity for the tape 10 than for the glue or film of adhesive 11.

,12 Will comprise a mixture or was emulsion applied.
