HT 51-88 - High-Tension Horizontal Foam Slitter

ESCO Model HT-51-88 is designed to cut polyurethane High Density foam blocks up to 51" (1295mm) high, 88" (2235mm) wide and 11' (3353mm) long. The maximum density of the material cut can be up to 6.0 lbs (96kg/m3) with an IFD/ILD of 200 or less.

Head Assembly & Table - Specifications

Independent head assembly rides on precision ball screws that are protected by flexible dust covers. The head assembly has a tilt range of 0-5 degrees of forward tilt.

Foam buns are transported through the saw by a powered table (shown) or a belt conveyor. Either version can be equipped with a vacuum to hold the material or air lift sections to assist in moving the bun. The vacuum and air lift are built into the conveyor assembly.

Table is driven by a 1 HP AC variable frequency speed controlled chain drive that is capable of moving the table up to 150 FPM (46m/min). Table height is 33" from floor.

Blade - Specifications

The Model HT-51-88 is equipped with a 3/4" (19mm) x 0.020" (0.5mm) serrated blade supported by 16" (406mm) diameter wheels. The wheels have molded urethane elastomer tires.

An optional blade sharpener equipped with long life "Borazon™" grinding wheels allows a knife blade to be used. Blade motor is 5HP and allows the blade to run at a no load speed of 4100 FPM (1250mm/min).

Standard Teflon coated blade guide, 0.085" (2mm) thick x 3.125" (79mm) wide, die spring tensioned, is provided with each machine. A heavy duty Teflon coated blade guide 0.314" (8mm) thick x 3.125" (79mm) wide and/or blade guide stabilizer are optional.

Operator Control - Features

Touch screen operator controls are mounted on a freestanding podium connected by a flexible conduit so it can be positioned on either side of the machine.

The machine is equipped with a Programmable Logic Control (PLC) that allows control of the cut thickness in increments of .004" (0.10mm) and has an indexing accuracy of +/- .015" (0.40mm). This is actual head movement based on encoder input. In the PLC program there are adjustments that allow compensation for mechanical tolerances and electrical timing that may change over time.
The PLC also allows for such added features as:

  • Batch cutting
  • Batch pausing
  • Set height command

Power Requirements

Available electrics are 460v 3ph 60hz, 230v 3ph 60hz, or 208v 3ph 60hz. Contact ESCO for other electrics.
