Toyota Super Jeans J34 Sewing Machine

The Toyota super jeans j34 sewing machine is a Toyota branded industrial machine targeted at the denim repair industry. Toyota’s entry into “premium” machines from its humble beginnings as an OEM manufacturer of cheap machines was spurred by competition from Taiwanese manufacturers, who were threatening Toyota’s core business in North America. Toyota, which owns Toyoda Automatic Loom Works (TAL) and Toyota Motor Manufacturing Canada Inc., needed to beef up its line of industrial machines and the super jeans j34 sewing machine is what it came up with.

The company entered into this segment after launching new versions of its own Toyota T-4 series vertical knee-type portable and Toyota T-5 series benchtop models with updated features including Toyota’s proprietary CT-3 controller and the Toyota Auto Top drop-in bobbin. Toyota had long ago made an important decision to use its own drive system, which derives a 50:1 gear reduction from an AC motor mounted on the main column of these machines (called CT-3), instead of conventional cams found in domestic models by Janome and Elna.

Toyota’s success is built on the Toyota Auto Top drop-in bobbins because they are said to be more durable than conventional steel bobbins. Some experts have suggested that Toyota combiheads and Toyota super jeans j34 sewing machine were designed with Toyota Auto Top bobbins included as standard equipment. The machine has removable upper arm plates with integrated adjustable top tension unit and a removable wide flatbed table.

Toyota super jeans j34 sewing machine is the only Toyota industrial model that allows for top tension adjustment without removing the needle plate, so Toyota redesigned the cam box on Toyota super jeans j34 sewing machine to accommodate this feature. Both Toyota combiheads and Toyota super jeans j34 sewing machine are equipped with Toyota’s proprietary single-point threading system for combination work.

With the Toyota Auto Top bobbin mounted on its front, Toyota combiheads can stitch through any thickness of fabric. Toyota combihead machines might be considered by some to be complicated because there are 22 functional parts: 4 mechanical buttons; 1 ribber spring; 1 flywheel cover; 3 presser feet (walking foot, overedge foot, quilting foot); 1 Toyota Auto Top bobbins; 3 Toyota Auto Top combihead needles (1/4 x 24, 1/4 x 18 and 5/16 x 18); Toyota Auto Top drive unit.

The Toyota Super Jeans J34 sewing machine uses the Toyota Auto Top 200-5J05A bobbin with an aperture of 5mm as standard equipment which is compatible with Toyota T-3 to T-7 models and Janome models equipped with Toyota Auto Top drop-in bobbins (note that the earlier white Toyota super jeans J33 model used a 4.5mm bobbin). The top tension assembly is adjustable from front right side without removing needle plate for one touch thread ing.

Toyota Auto Top combihead model CT-3 utilizes Toyota’s proprietary drop-in bobbin system for automatic top tension adjustment for all thicknesses of fabric and eliminates hand wheel adjustments with its single point threading capability.

Toyota combiheads are also equipped with a unique one-step reverse mechanism that enables the operator to turn the machine around without stopping sewing: A function Toyota calls “backward sewing”. Also, Toyota combihead models have a PLC (programmable controller) mounted on them which can be programmed for computerized industrial stitching for work uniforms or other industries requiring high volume production.

Toyota adopted an approach of using a Toyota Auto Top drop-in bobbin on Toyota combihead models and Toyota super jeans j34 sewing machine. Toyota had for years worked in the background on development of what it calls Toyota “Auto Top” drop-in bobbins because they are said to be more durable than conventional steel bobbins, which the company feels is important for industrial sewing machines that can sometimes run 24 hours or more each day. Some experts have suggested that Toyota combihead and Toyota super jeans J34 were designed with better belt drive and it made possible by Toyota’s proprietary CT-3 controller, which derives a 50:1 gear reduction from an AC motor mounted on the main column of these machines (called CT-3).
