摘要:
The present invention relates to apparatus for edging reinforced elastomeric fabric and a preferred method for the operation thereof. One embodiment of apparatus includes a frame, a table for support of the elastomeric fabric, at least one extruder assembly adjacent the table for the application of a suitable elastomeric material directly onto an edge of the elastomeric fabric and means for moving the elastomeric fabric over the table. In an alternate embodiment, the apparatus includes a frame, means for support of the elastomeric fabric and at least one extruder assembly adjacent the means for support for the application of a suitable elastomeric material directly onto an edge of the elastomeric fabric. The preferred method includes the steps of passing the elastomeric fabric over the means for support, extruding the elastomeric material through the head and imparting a first edge therein compatible with an edge of the elastomeric fabric and joining the extruded material to an edge of the elastomeric fabric by forcing the material into substantially all of the exposed surfaces thereof.
摘要:
The present invention relates to an apparatus and method for making sheets from reinforced elastomeric ribbon. The apparatus has a lead-in mechanism on which the ribbon is received for preliminary orientation. The apparatus also employs a transfer mechanism that incorporates a shuttle head which is supported by a primary carrier disposed over the assembly mechanism. The shuttle head is capable of being protracted from its normal position over the assembly mechanism to a position over the lead-in mechanism where it is also engaged by a stabilizing carrier which assures precise orientation of the shuttle head during its operative movements with respect to the lead-in mechanism. So stabilized the shuttle head: engages and grasps the ribbon presented by the lead-in mechanism; raises the ribbon off the lead-in mechanism; retracts to position the ribbon above the assembly mechanism; and, accurately deposits the ribbon on the assembly mechanism. A guillotine mechanism severs the incremental strip deposited on the assembly table from the ribbon. After the shuttle head disengages from the incremental strip the guillotine mechanism is moved out of contact with the incremental strip so that the incremental strip can be transferred laterally by an indexing mechanism to the degree required for receipt of a successive incremental strip without inadvertent interference between the strip, or strips, being indexed and the guillotine. To achieve indexing the assembly mechanism employs a continuous belt that is accurately indexed by a unique arrangement of interacting brake and transport clamps. For most purposes, successive strips will be deposited in continguous, lateral juxtaposition, and in order that the successive strips stick together a stitcher is provided to cycle a stitching roller along the abutting edges of successively deposited incremental strips.
